Hey mate, as others have said, try Proud. You could take a look at Barfly and see if they have any music on.
If you do fancy music, then your places of choice are:
The Dublin Castle - Lots of unsigned music promotor nights on here.
The Jazz Caf?® - Big names, jazz, hip-hop, folk etc.
Underworld - ARRGGGHHHHH... DER DER DER, DER DER DER.... ARGGGGHHHHH I tinkle ON YOUR MUM.... type music
Electric Ballroom - Gets all sorts, see what's on
Koko - bigish venue that has some cool bands on, worth looking up as well.
Barfly - Same as Dublin Castle, though with slightly more "established" bands
The Roundhouse - Good venue, again all sorts (Apple use it for their month of gigs thing)
If you fancy a good caiparinha or mojito and a friendly crowd, then Casa de Sogra, opposite Barfly, is a decent place to go and have a drink. If you get talking to the owner about Cachaca, he'll likely chew your ear off and give you a few free shots whilst he's at it.
For eats you have absolutely anything you can imagine, but special mention for me are the Mango Rooms (Carribean), Gilgamesh (Pan Asian) and Belgo (Belgian), though the Belgo in Covent Garden is better.
Have fun and stay safe, it's a crazy place, is Camden
