Yes, it's everywhere. I have 19 year old, in college and a 15 year old. We are all music junkies. There are lots of venues around Austin. Don't know exactly what type of music you're into, but I'll give some links of the places we go. Most of the shows we see are NOT in Gigantic commercial venues, hate those.
To start off with there's this music store on 6th street called Wild About Music, my son and daughter love it. http://www.wildaboutmusic.com/
it is pretty amazing even if you don't buy anything.
1. http://mohawkaustin.com/ The Mohawk, nice venue with indoor and outdoor stages, we recently saw The Bouncing Souls here. http://www.youtube.com/watch?v=1so_jhbmbKs this youtube clip was shot form one of the multiple viewing balconies, you don't have to be down - "in it"
2. http://stubbsaustin.com/concert-listings/ I've been to multiple shows at Stubb's Here's the last Rancid show: http://www.youtube.com/watch?v=TdGsCWOMYis this is from Stubbs, larger venue similar to the Mohawk, much larger!
the Moody Theater also known as ACL-Live http://acl-live.com/venue
The Parrish on 6th St. http://www.theparishaustin.com/
and so much more, have fun and don't forget to live!
