Well Peter, in no particular order, off the top of my head and based for the most part on the people or music I spend the majority of my time listening to, and also really songwriters, more than bands as such, the list would look a little something like this:

Bruce Springsteen, Johnny Clegg, David Baerwald, Neil Young, Roger Waters, Paul Kelly, Bob Dylan, John Hiatt, David Byrne, Robin Auld, John Butler, Shawn Colvin, Tom Petty...

And yes, I know that's 13, but hey, it's my list....
