Kiyoshi Tanaka a Japanese drummer was well represented in releases of the '70's Quad era. Here're some Quad titles with him on them (a few of which I own)-

I happened upon this release from 1972 in QS LP format, while doing some research, but the LP sells for outrageous amounts; then I noticed a fairly recent QS encoded CD version of it (which is fairly unusual these days.) This one was available at still relatively high dollars for a CD, but I put extra value on such things, since it is truly Matrixed Quadraphonic! So of course I had to pick one up
Here's the original release-

and here's the QS CD release which I decoded through my Involve Surround Master v2.

This is some wild Live '70's Psychedelic Rock, that give tribute to various British Rock Bands - i.e.
Track 1 - '
Trip To West Coast From Britan' -> The Grateful Dead, Atomic Rooster, The Mothers Of Invention Zappa & Uriah Heep.
Track 2 - '
Echos' -> Pink Floyd
Track 3 - '
Jimi Hendrix Mad Song' -> Jimi Hendrix
I'd say it's a fairly descent mix for QS and the fact it is a live recording. Seems to be more of a side to side mix than more discrete sounding front to rear.
