It seems the Bad Plus have thrown down the gauntlet. (We're finally in a blogwar -- does that mean this blog has truly arrived?)
I will attempt to muster a suitable reply. This may take some time -- I've got to prepare for my first lesson with Hollenbeck on Tuesday, amongst other things that need doing. In the meanwhile, why don't you pass the time by playing a few clips from Bob Belden's video collection? Some amazing stuff, including relevant footage of '70s Miles gigs.
[N.B. For some reason, Paul's video file has an extra ".txt" extension at the end, which makes things go all pear-shaped -- but if you download the file to your HD first, then remove the ".txt" from the filename, all is well.]
