Flashback's mostly second-hand stock is treated with utmost respect. There are usually a few boxes of bargain basement 12-inches going for pennies outside the front door, but inside stock is scrupulously organised. The ground floor is dedicated to CDs, with rock and pop alongside dance, soundtracks, soul, jazz and metal, while the new stock of urban and dance records, especially 1960s psych, garage and hip hop, is a well-kept secret among DJs. The basement, though, is vinyl only: an ever-expanding jazz collection jostles for space alongside soul, hip hop and an astonishing selection of library sounds (regularly plundered by producers looking for samples). Those not inclined to rummage can search out long lost gems on its website.
