Overwhelming. It’s the word perhaps most used when describing Austin’s South by Southwest. And while you would think the festival has become, well, less overwhelming over the years as we become accustomed to seeing the festival’s annual bill featuring a thousand-plus acts, it really doesn’t work that way. Today, SXSW 2010, which goes down from March 17-21, announced several hundred new acts, including The Magic Numbers, Alberta Cross, The xx, Rhymefest, Efterklang, Califone, Neon Indian, Marina & the Diamonds, Cymbals Eat Guitars, CoS’ favorites Kittens Ablaze, and that Art Brut side-project Everybody Was In The French Resistance…Now!. Click here to see our list of confirmed notables, and then realize we still have several hundred more acts yet-to-be-announced. Overwhelming? Duh.

On a side note, now seems like a good opportunity to remind you of our SXSW Day Party with Sled Island Music Festival. Click here for more details!
