I have just signed up to your site. It looks very interesting and I will check it out more but one question arises for me and that is 'backup'!. I play Banjo, Guitar and Mandolin. There are plenty of tuition methods available for learning Bluegrass tunes but not much in the way of backup! What do you guys do while the other instruments play their lead breaks? I would love to have the addition of these files. There are a few DVD's available like Janet Davis and Acutab that are good but I don't seem to be able to transfer this knowledge into practical usage' It's a bit like learning the alphabet but not being able to make a sentence out of it. Is it just me?
I don't think this is really what your asking, but your topic "Backup Lessons" caught my eye. For me, what I really need is the backup tracks to play along with. While I value the lessons the instructor gives and sometime I learn the break they are teaching, I think a offering of some backup tracks would be a real marketable item. For me, I want to be able to jam with a recording but be able to try out different leads to the rythem.
There was a book called BackupTrax which was great but were mostly instrumetal tunes and a limited number of songs. I wish someone would take this idea and do more songs with it.
