Stanley Clark's bass solo on this disc is the best (MCH) recording of acoustic bass I am aware of (by a mile). I don't particulary care for a lot of the electrical stuff, but the acoustic recordings are to die for. Al diMeola solo is a far better recording of solo guitar than for example the Jim Reynolds / Dave Matthews disc, which is pretty good in its own right.
I thought I had some acoustic-set unplugged DVD's in my collection, but alas, I couldn't find any.
thanks for the heads-up, I'll be looking for this particular BR in my travels.
