SXSW Interactive has forged a reputation as not only a breeding ground for the hottest new tech companies and apps on the market (Hi Foursquare), but also as a place that can introduce the world to companies that can change the way humans interact (how's it going, Twitter?), and the music industry is not immune to its advances. As SXSWi has grown, so has its influence on the music community, and this year's Interactive fest (which runs from March 9-13) has put up a bunch of parties and events that tap into that connection.
We've compiled a list of as many music-related events as we could come across (though more are being added every second) and posted them below.
Friday, March 9
Epic Interactive!  (7pm-1am) - Free drinks on Do512 at The Belmont and a three-band showcase curated by personal security app AirCover that includes Delta Spirit and Dale Earnhardt Jr. Jr.
TechKaraoke  (8pm-2am) - live band AND between-set DJ karaoke at The Stage on 6th, for all those moments when you are networking so intensely with SXSWi cohorts that you just can't help but break out in song with a live backing band.
Saturday, March 10
Spare Beats  (2-10pm) - All day long DJ showcase at Molotov bringing in acts from across the country to spin for the partying crew, including Get Right Kids + Thick As Thieve$, Table Manners Crew, and Roxy Cottontail, to name a few.
