I'm meeting some friends from out of state in Austin for the day so their misguided son can tour the tu campus. I have not been to austin in quite a while myself so I'm looking for recommendations of things to do. They'd like to see some live music on 6th Street -- can you find that during the day? I'd also like to get them some good BBQ. Anything else in Austin that might be good for them to see/do? It's their first real trip to Texas.
