SteveS.: Shades of Woody Allen's SLEEPER.
Obviously, the maker of this contraption put some time into assembling it. But the video presentation was SO hokey and contrived (the body movements and expressions of "soul") that I found it a complete turn-off.
And I still haven't settled on the value of a "blues scale" instrument. Like posted above - maybe for a circus act by some far-out R&R actor (I won't say performer), but otherwise . . . why? Probably just because he could . . .DAVE
