If you're based in New York you've got a weekend of music hacking coming your way. On the 12th and 13th the General Assembly will be taken over by Music Hack Day and used as a hotspot to check out what's up with music + software + mobile + hardware + art + the web.

Organised by NYHacker, General Assembly, SoundCloud and The Echo Nest, the two day hackathon runs from 9am-7pm on Saturday and 9am-5pm on Sunday.You can either present your own projects, or just show up on Sunday for the demos that'll be shown on the day. Should be cool. Register here, it's free.
