Somehow, I managed to miss the announcement several thousand others apparently heard for this epic show Mumford and Sons played on the lawn of the LBJ Library Saturday night, ending SXSW 2012 on a high note. (Edward Sharpe and The Magnetic Zeroes and Old Crow Medicine Show also played.) Joining M&S on "The Cave" was the Austin High School Band, reprising their performance with during 2011's "Railroad Revival Tour." That performance was documented in the film "Big Easy Express," which had it's world premiere during SXSW Film earlier in the day. Next year, I really need to learn how to use that Twitter thing.
