Welcome AggieBethie - from a fellow North Texan. I live in Dallas and have been Mudcatting for just over a year. Great place, and yes there's some great music in Texas - of the "folk/celtic/renaissance music" you mention. In fact, you need to be sure to come out the North Texas Irish Festival (second biggest in the US) this March 2, 3 and 4. Also check out the thread Spaw quotes above - a number of the DFW area Mudcatter attend this session in Fort Worth ... and if you know of some "folk/celtic/renaissance music" music venues at your school, let me know, 'cause there are a few of us looking to add some new music spots to our list.

This is a good place to find out what's up with that sort of music anywhere, not just North Texas, and in fact, not just the US. Glad to have you!
