606 Club

You'll descend into this Chelsea basement expecting pretension, but instead find yourself in one of London's most unpretentious live music venues. The 606 has been hosting jazz, blues and funk acts since the mid-70s—the kind of place where serious musicians come to play serious sets, and audiences actually shut up and listen. The room's small enough that you can practically feel the drummer's energy, and the bar staff know their stuff. It's the sort of night out that feels properly London: a bit rough around the edges, genuinely welcoming, and utterly devoted to the music.
