The Music Hackday continues its endless journey in the search of the best music hacks around. After taking London, Berlin, Amsterdam, Boston and Stockholm by storm, San Francisco is the next city to get its fair share of music hacking and next generation music applications on May 15/16. If you haven’t heard of the hackday yet, it’s a full weekend of hacking where total music geeks like us people get together and create something beautiful out of music, hardware, art and the web.

So, how do projects which saw the light of day at a Music Hackday look and sound like? Check out our personal favourite citysounds.fm, which lets you listen to the latest tunes from your city. Or dive right in and watch this vid from the Hackday in Amsterdam in April this year:
