Peckham trio Beaty Heart make tropical music that somehow manages to avoid the usual trappings of pastiche or appropriation. It's honest, involved and well researched. Taking influence from a chance meeting with a former school-time friend, Beaty Heart talk to us about the organic development of the single 'Seafood'.

First, watch the video to 'Seafood', which plays out like a toga party held at Willy Wonka's chocolate factory, with the trippy mildly unnerving undertones of Labyrinth [the film with Bowie] - not a band thing at all.

"When I used to go to school in Cape Town, I had a friend called Panache. Panache was the fastest runner in school and played tennis for the national youth team, he didn't say much but everybody liked him. His dad was a minister from Zimbabwe who ran a large church in the area near the school. I remember one birthday, Panache's parents bought me a tiny bible that came with a plastic magnifying glass, but I never really used it much. When my family emigrated back the UK, I lost contact with Panache; he didn't really buy into MySpace or MSN.

"A few summers back however, whilst studying in London, I was working as a strawberries and cream server at Wimbledon, where by chance I bumped into Panache, who had been playing in the Juniors' competition that year, which was strange because I could have sworn he was over the age limit by a couple of years (but I didn't mention it). He told me he had been knocked out in the first round the day before, and was probably going to give up his pursuit of being a professional tennis player.

"He seemed pretty down about it, so I invited him to come and party hard back at my place in Peckham, where I was living with the other guys from the band at the time. All the boys got on well with him, which was no surprise because when Panache let his hair down he was a hoot, and we ended up getting very, very drunk; climbing on roofs, hitting volleys down the street with Panache's racket, that kind of funny shit. Later on we got talking about music, as you do, and Panache put on these awesome Zimbabwean tunes. One group we all particularly enjoyed were called Mbira Dze Nharira, a tribe who Panache informed us lived near to Harare, where his Dad was brought up. After that night we never heard from Panache again, I've tried to get hold of him but can't track him down, none of my old friends in Cape Town know where he is either.

"A year or so ago, during a practice session, me and the boys from the band were reminiscing about that crazy night with Panache. We put the Mbira Dze Nharira record on again, ended up sampling one of the tracks, and wrote 'Seafood' entirely in that practice session. Lyrically the song isn't about Panache, nor is it about seafood. But every time we play it we think about that night we spent with Panache a few summers back. I only wish he'd get in touch."

The band's debut album Mixed Blessings is out now on Infectious Music.
