This year's fun fun fun fest lineup is EPIC!!! Definitely befitting the 6th anniversary of the little festival that could. For the last 5 years, it's been squeezed into Waterloo Park in the middle of Austin. This year, it's so huge they've had to move to Auditorium Shores and I'm not even sure beside Lake Austin is enough space to contain this much awesome.
I've been to a few (including the first way back in 2006 to see Austin's own Black Angels). It's a well-organized weekend of music and comedy with plenty of local food and beverages. Definitely one of America's best kept music secrets so far. And with bands like this coming, there's reason you shouldn't either.
