London music

There are some more niche stores around catering for Rock & Roll or World Music, things like that.

Oh and the bi-monthly record fair at Spitalfields Market is often really good, it's a nice spot too with plenty of other stuff to look at/places to eat, there's one on the 16th - https://oldspitalfieldsmarket.com/events/vinyl-market

hello friends ... what is the current best concert calendar for London, particularly with regard to indie / punk / experimental stuff? already checked some venue sites and Time Out London, but wondering if there's something more comprehensive to help me make sure i don't miss anything.
