Have you heard Alabama Shakes yet? This soulful band made a big splash at SXSW, secured an opening slot this spring on Alabama Shakes's solo tour and will release their excellent full-length debut, Boys & Girls, on Tuesday (April 10). It's a fresh mix of Southern rock and '60s R&B, where you can hear traces of Otis, Aretha and Janis mixed in with Shakes singer Brittany Howard's fierce howl. And to celebrate the release date, MTVHive.com is streaming their entire concert from New York's Webster Hall as part of their Live in NYC series. You can stream that show here on Tuesday night at 9 p.m.
