Thanks for the positive words and the input. Hopefully I'm still improving in terms of making the tracks sound natural. I am a poor musician so I think my "live" tracks would destroy the sound. I do have live bass (by a good friend) on 4 tracks I've done and a live guitar solo (my son's guitar teacher) on 1 track as well. I do think it works great to have them mixed together as Tom Adams and others have done. Take care. Greg
