Traveling to Cardiff

Hey, I am hopefully going to be traveling to Wales this summer and wanted to know what's going on that time of year. I'm aware of gigs and stuff happening and I'm looking for less touristy stuff to enjoy.

I'm 32, male, bisexual and an artist and musician so any good open mic bars, gay bars, open pottery studios and the best galleries or museums to visit.

Or alternatively can anyone send me links to local stuff happening in Cardiff, preferably a website that someone pretty crap navigating websites like me can figure out lol

Thanks in advance.
