Here's the second edition of our new monthly column, the 405 Retrospective. Each month we're going to remember some of the great music of the past and bring it back to you – with so much music being released every week, we often forget that there's countless artists, records and songs already out there, just waiting to be rediscovered. Here are the best tracks that have been kicking around for a while.

Last June we had the Queen's Diamond Jubilee, a stacked card of pop legends throughout the ages, and Robbie Williams, performing for our royal matriarch. We were preparing for one of the biggest events in modern British history in the form of the 2012 Olympics, and preparations were well underway. In terms of music, we had career lows from Linkin Park, the Offspring and the Smashing Pumpkins, but fortunately, to balance out the avalanche of twaddle, we had the debut from DIIV. Oshin was an essentially flawless album, and the brilliance of it was so overpowering that it breezed onto many end of year lists and garnered the dreamgaze outfit oodles of plaudits.

As Westlife turned ten, Fleet Foxes released their seminal eponymous debut. The Seattle-based folksters floored critics with their first full-length outing, leading to many institutions naming it an instant classic and one of the most important American records of all time. Big words for the quintet to live up to, but with ethereal harmonies and thought-provoking lyrics, as well as pretty nifty fretwork, they won hearts over around the world.

June 2003 was the month that R.E.M., Radiohead and, erm, Moby headlined Glastonbury, at one of the largest gatherings in the events history. Across the Atlantic, Christina Aguilera and comeback king Justin Timberlake set out on a joint tour of America (aptly titled Justified & Stripped) – riding on the back of pop classics like 'Dirrty' and 'Cry Me a River'. Fun fact: they were supported by a fledgling Black Eyed Peas. Back before they became the stadium pop-rockers they are today, Biffy Clyro also released their landmark record, Vertigo of Bliss. Recorded in just one day, it spawned career-defining classics like 'Questions and Answers', and 'Toys, Toys, Toys, Choke, Toys, Toys, Toys'. N'aww, just look at how young they are.

Fifteen years ago, Godspeed You! Black Emperor released F♯ A♯ ∞. Well, technically it dropped in '97, but the expanded re-release was in '98. The Canadian post-rock icons reshaped the conventions of the style with their debut, melding gut-wrenching emotion with expansive soundscapes, flippant dynamics and climaxes that surpass the term 'apocalyptic'. It's a must-have for any enthusiast of the genre, and one of the most poignant avant-garde rock albums ever released.

In the tail end of the 70s, the 50s were reborn – yes, the film adaptation of Grease opened at cinemas worldwide. The success was so great that it still remains the highest-grossing musical in the USA. Also going on in June '78, the Boomtown Rats put out their second LP, A Tonic for the Troops, which featured classic single, 'Rat Trap'. The post-punk/new wave group, helmed by altruistic Irishman Bob Geldof broke up in 1986, and resisted the temptation to reform – until now. They perform their comeback set at this years Isle Of Wight Festival.

In June 1963, a teenage Lesley Gore released her first offering, I'll Cry If I Want To, featuring massive hit 'It's My Party'. A staple of weddings and cheesy discos for decades, it's left a lasting legacy on pop music for fifty years. The album also harboured singles like 'Cry Me a River' (no relation to the JT hit) and 'What Kind Of Fool Am I?', and was produced by accolade-laden R&B producer, Quincy Jones. Gore never really repeated the level of success that this album had, led by her youthful energy and teen-pop chops, but she'll be forever remembered for shaping modern pop and soundtracking countless bouts of dad-dancing.
