My daughter is doing a music degree at Cardiff Uni. Of the places she applied I think Cardiff was the only one which asked for an audition before offering a place, and it was very relaxed and friendly, I think she just played one of the G8 pieces she was working on and had a chat with the tutor. She was nervous about it, but found it fine, and Cardiff ended up as her first choice. I think Leeds asked her to do an audition at the offer holder day, but she already had the offer, so I'm not sure what the purpose of that was - maybe for the university orchestras/bands. I went with her to 4 offer holder days (Cardiff, Leeds, York and Durham) and they were all very friendly and welcoming.
