A few more acts and shows have been announced on the Noise Pop site.

Here's an updated list of my probable shows (so far):

2/28 - Sebadoh/Love of Diagrams @ GAMH; Will Sheff @ Swedish-American Hall
3/1 - Lyrics Born/ The Coup (you gotta see The Coup!)/ Lifesavas @ The Fillmore
3/2 - Autolux/ Snowden/ Malajube @ The Independent (still the strongest line-up of the festival)
3/3 - Clinic/ Earlimart/ Sea Wolf @ The Independent OR The Ponys/ Lemon Sun @ Bottom of the Hill -- this is going to be a tough choice! There's also a fine lineup of bands that get played on BAGeL Radio, it's at the Rickshaw Stop: Spinto Band/ Dios Malos/ The Changes/ The Old Fashioned Way. Oy.
3/4 - Midlake (afternoon show) @ Bottom of the Hill

I will update this again when more bands/lineups are announced.
