Thanks for some great ideas and introductions. I find that listening to Vital Bits, 6am every Saturday and Sunday on 3 RRR FM often leads to me to music I've never heard before, even from established artists like Neil Young. Also more obscure stuff such as Ian Harper's "when an old cricketer leaves the crease" - different, but nice.
A favourite band I never saw mentioned here is Little Feat, great southern rock. If you like them, try Marshall Tucker Band too.
(I first got on to Little Feat by a mate whose son played with a bloke who knew that Linda Ronstadt's father played backing on a particular track - it's as good a way as any to discover a new band!). Hi Paul, wherever you are.
