Studying Creative Expressive Therapies at Derby Uni

I have an interview for creative expressive therapies at Derby uni, doing to music pathway.

I'm quite nervous because this last year and a half I have been working (gap year!) and am a bit out of the swing of things music wise... all my friends went off to uni and I haven't really done anything musical to be honest, for a while...

Well my interview/audition is coming up in about a month, and they're asking to 2 contrasting pieces. Any advice on what this really means? Will doing one song on the guitar, and one on piano be contrast enough? I'm out of practice and freaking out!!

Any advise about what the interview entails would be awesome, or anyone who's in a similar position want to talk about it??
