Music is a perpetual muse in the ever-fickle fashion world. Former Dior Homme designer Hedi Slimane is influenced by the new wave of British bands, chiefly Babyshambles and Franz Ferdinand; Karl Lagerfeld of Chanel and Fendi is known for his legion of iPods; Viktor & Rolf have featured live performances from the likes of Tori Amos and Roisin Murphy in their runway shows; and thanks to Vivienne Westwood, punk rock is synonymous with fashion and subversion of the status quo. This season is no different, as a range of ready-to-wear lines take inspiration from the rock 'n' roll lifestyle and even German experimental bands. Diesel's autumn/winter 2011 menswear collection tells the coming-of-age tale of a wannabe rock star who daydreams about freedom while playing music in his bedroom. Chunky cardigans, cotton flannels, pyjamas and fleece loungewear in colours such as yellow, royal blue, purple and camel keep him company on his journey to potential stardom and manhood. Graphic T-shirts evoke indie and punk music, record sleeve design and electro flyers - think British rocker Pete Doherty of Babyshambles. Accessories include hunter caps with fur, metal studded belts and soft leather bags. With the slogan 'Live the rock-n-roll lifestyle', Tommy Hilfiger Denim's latest collection centres on a group of adventurous youths appreciating the beauty of the vast American landscape. The collection offers an eye-popping palette of colours to choose from - the signature Tommy Hilfiger red, white and blue, orchid hush, aqua sea and ivy green. With a myriad of inspirations, such as Huckleberry Finn and nature, the collection offers chunky sweaters, brushed flannels and Sherpa and waffle knits for musically-inclined young men. Down jackets and utilitarian wool coats keep them warm and cosy in winter. The leading man of Armani Exchange's autumn 2011 collection, 'Metropolis XX', is athletic and has a penchant for travelling on rollerblades, boards or by bike. By day, he navigates life with smoky printed shirts and rugged leather jackets. By night, he unleashes his wild side with plaids, striped tweeds, urban Fair Isle, cowl neck pullovers, aviator trousers and suede-trimmed blazers. Grey, which is used throughout the collection, is a nod to the brand's love for cities with an unflappable energy, from New York where indie gems like Interpol are based, to New Orleans where jazz maestros, such as Louis Armstrong, hailed from. Paul Smith Jeans collection is true to the designer's signature childlike style. Inspired by Berlin's music scene in the 1970s, which witnessed David Bowie collaborating with Brian Eno on the era-defining Berlin Trilogy, the collection features colours such as washed acid pastel green, orange and pink, that are reminiscent of the aesthetics of German experimental rock bands Can and Neu!. Oversized jerseys and chunky knitwear also pepper the collection. Agn?s b.'s autumn/winter 2011 Homme collection features an array of inspirations, including rock 'n' roll. Tipping its hat to musician-writer Patti Smith, the collection channels her brand of androgyny. With menswear like sparkling suits and tight leather pants, the collection is ready to take centre stage.
