The Cellar is without doubt at the forefront of the Oxford music scene, being independent, in touch with the youth, and about music more than just money.
Probably about the best night in Oxford is Bossaphonik, monthly on a Friday, having firmly made its mark on the world/jazz circuit, and so always hosting world class live music acts...
There are also well established regular nights for DnB, Hip Hop,Indie rock and Reggae.
Keep up with what's happening on their website, as well as their facebook page.
The Cellar is certainly my 1st port of call in Oxford for music.
