I've got you on this one!
In Glasgow city centre, you need to check out Monorail Records, which is in a great pub called Mono. It has a great selection of local and international stuff. There is also a place called Love Music that's possibly more second hand.
If you fancy y a gig, look for stuff on at the Barrowlands or King Tuts, both are legendary venues.
I'm maybe a few years off current for bars, but you should be fine in the city centre or Merchant City areas. The Pot Still is a famous whisky bar if you fancy that.
Consider going to Kelvingrove Art Gallery - it's free, and is great. You can get the underground out there.
Have fun! Happy to answer any more questions you have.
