This trio is one of my favorites! Metheny is great. Also, any guesses where the drummer is from??? You guessed it Des Moines, Iowa. Bill Stewart was a Roosevelt Grad. Check out this video of "Lone Jack".
Here's a video of him playing his "picasso guitar" made by Linda Manzer. I think this might be part of "Into a Dream".
Here's an awesome version of "Proof" directed by Jim McNeely at the North Sea Jazz Fest [I actually played at this festival with the Drake Jazz I]. Beware this recording starts and stops a lot...
Here's one of Metheny on a "Manzer" Baritone Guitar playing a variation Norah Jones' "Don't Know Why"
