Guy - you can have lots of fun recording round one mic. I know someone who recently recorded a punk band around a single mic!

Mind you it was a VERY expensive Soundfield (originally intended for recording orchestral performances I believe).

I've recorded a bluegrass outfit using only ambient mics - but soon reverted to a mix of this and close micing - I guess my instinct as an engineer is to make sure I can get control of the mix later in the process!

As regards Mudcatters CDs, I have recorded tracks on and mastered the new Julie Ellison CD "At Last". You can hear samples at:
