Bloc Party's Kele Okereke has a reputation for being a tad frosty with the media, from his NME-baiting antics of yesteryear to his vocal disdain of celebrity culture and the associated dross. However, even with the embargo on band-related endeavours, when the opportunity to interview my favourite musician of all time arose, I leapt at the chance. I'd heard rumours he could be, for lack of a better word, a dragon - but it was worth taking the risk.

Jitters aside, the time comes to call. It doesn't come as much of a shock when he answers the phone, and after niceties blurts "How long is this going to take?" I assumed that this was going to set the tone for the interview, and braced myself, meekly promising it not to take too long. Kele presumably clocked his previous tone. "Forgive me, I didn't mean to be rude." I unclench.

Kele, representing Bloc Party, is curating the latest in !K7's Tapes series. Following Foals and The Rapture, he's assembled a 60(ish)-minute mix in the style of an old-school mixtape, supposedly with a different mood on each side. "I don't know what you mean..." says Kele when I ask him to explain what he's done with each side of the tape. I tell him I got my notes from the press release. "I haven't read the press release. There aren't two different sides. It's a journey. It's a collection of music I like that roughly tells a story, starting from what I listened to before Bloc Party to what's inspiring me now. It's a compilation of stuff I like, I guess."

It's easier to relax and chat freely now in the knowledge that, despite the chatter, Kele's actually very pleasant - nervous, and a tad defensive maybe, but polite, genial and fascinating to listen to. Show me a musician with a better vocabulary.

Given Kele's prominence in dance music and the Berlin scene (much of Bloc Party's second LP Weekend In The City nods to the German capital), it's surprising he's not partaken in the Tapes series sooner. Diehard fanatics of the angular indie side to Kele will probably be fairly nonplussed at the dance-shaded sprawl that unfolds on the tape, but for those coming to terms with the electronic, clubby side to London's most reticent act, this will answer a lot of questions. It gives credence to the band's claim that dance music was their chief inspiration from the start. However, even though it's waving the Bloc Party flag, it is only Kele who's had a hand in its creation. "I think these things, while they may be under the banner of a band, are always going to be the result of an executive individual mixing it. I was conscious of trying to reflect the music tastes of the band as a whole, so there's some garage, some post-rock, some stuff that we all liked in the beginning of Bloc Party."

One relic of his group efforts is given a shiny rework for the tape. 'Obscene', from the band's recent mostly-lauded EP, Nextwave Sessions, is torn asunder by Kele himself. "The original is quite melancholic. It's a ballad. I wanted to try something more uptempo, and with this kinetic, house feel. The great thing about remixing is that you can take music and focus on one thing you like, then just construct a new narrative with it." I ask him if remixing is something he'd like to do more of, after all, his work on MS MR's 'Fantasy' was superb. "I'm totally into remixing at the moment. It's kind of arrogant, like 'this is how I think this should be heard', which for someone like me appeals quite a lot." I almost miss the wryness his delivery is so parched. "It's about constructing a narrative. I've never been precious about people doing it to our music at all, which I think its a good approach. I've never been caught up in 'I've written it this way and this is how it should be.'"

Kele is pleased with his mix, and isn't afraid to let it be known. "I quite like lots of moments. The one I'm most proud of is the segue from Double 99 to Fela Kuti 'cause it's quite surprising to go from a full on two-step banger to this Afrobeat thing. It think it works quite masterfully." He's not wrong to be impressed with his efforts here. The transitions are fluid, almost invisible - you can tell this is a mix with ulterior motives. He wants you to dance. "I like how particular dance music is, how your response to it is a physical reaction, and how it's probably the only genre that elicits an immediate reaction. I like that. Music is very powerful, and it's something I've devoted my life to understanding and creating... I think that the way dance music moves the dancer is sublime."

This tape isn't the only extra-curricular activity that Kele is involved with. His long-awaited prose project, for example. "Hmm... It's in the pipeline. I'm working on a novel as we speak, not an anthology of short stories anymore," Kele seems enthused moreso by the discussion of his writing than anything else so far. "It hit me that I had an idea about where something should start and where it should end, and I decided it would be more useful as a novel than as a fragmented set of stories." Though clearly excited about the novel, he's also very careful not to let anything slip.

When it comes to dance artists, Kele's got a theory. "I guess there are electronic artists making music, and there are those who are DJs that when they play construct a story. That's something resonating with me a lot more now, and I like this idea of watching a DJ and seeing what they do." Are there any in particular that he's a fan of? "DJ Koze is someone that I really enjoy. His latest release Amygdala is great... Jamie Jones and Seth Troxler's selections are on point. Danny Krivit, this DJ from New York, plays amazing soulful house, which is my favourite music to dance to." When he's not shaking his stuff, Kele rather enjoys being behind the decks. "I try to have fun. I'm lucky that most people don't know what to expect, because they mainly know me as this singer in a rock band... They're curious, and that means I have a blank canvas. I try to tell a story over the two hours or however long, and I try to ensure there's movement. Some evolution too, hopefully." Though he has an m.o. when it comes to DJing, he doesn't like to plan ahead. "The trick of a good set is to not be too prepared, and just respond to how the crowd react; it's about not having the blinkers on, looking at the crowd and anticipating their reactions."

Even though we don't talk Bloc Party, Kele offers some titbits anyway - nothing major, but enough to prove he's not shied away like the blogs circulated immediately after their Latitude slot, and he continually talks of Bloc Party in the present tense. He's keen to note that there's still a future without overtly mentioning it. Previously, he's stated Bloc Party's future in regards to his !K7 tape plainly: "If anything this will be to the betterment of Bloc Party... It's like having an affair, then being able to come back home and realising what it is that you have. I don't think exploring this electronic world will be to the detriment of Bloc Party. Quite the opposite."

He's got other irons in the fire as well as this tape, remixes, writing and DJing, having recently provided vocals for RAC's 'Let Go', and in recent memory working with Sub Focus, Hercules & Love Affair and others. Are these kind of collaborations something he's perhaps gravitating towards nowadays? "I love collaborating. It teaches you something about songwriting. Bloc Party is a collaboration. I like working with other musicians, and it's something I've always done. I love the exchange of ideas." And what about solo material? After 2010's The Boxer and its 2011 follow up EP, The Hunter, maybe he's got something else lined up. "I'm a creative person. Never say never..." He takes a beat to ponder. "Never say never."

After we finish discussing what keeps him busy, he signs off with "Have a lovely rest of the day!" It seems that he's been painted in a very particular way these past few years. Today, Kele couldn't be further from what I'd imagined. Maybe it was all fabricated, fudged and skewed. Maybe some of it was true. Either way, he's proud of the results on his !K7 tape, and seems eager to dabble in a wide variety of activities. No doubt we'll be seeing a lot more of him in 2014.
