I always liked the simple raw performances by some very well known bands appearing on different programmes by the BBC.
John Peel sessions and Old Grey Whistle Test being some of them.
I'm assembling tracks that firstly sound okay, and then will have a raw live sound about them and not as polished as the original studio recordings might have been.
I think you may remember Cowboy Song by Thin Lizzy from an old mixtape, now that would be a good example of the nice raw sound I would be looking for,
You know, the hiss from the amps and the snare drum vibrating from the notes of the bass guitar!
