Steve is an old friend from the beginning of the '70s from Madison. He started as a pianist and has taken up saxophones.
Do a search on his name.
He has stuff to sell.
FWIW, the session in question produced 6 "tunes" totaling 43 minutes. In addition, I have access to 2 more performances for another 9 minutes, performed by the same personnel. Looks like a cd to me.
At least Reisner and Russell capture some feeling of the time which is missing from many since. Not easy to discount (in my book).
Some of this is more important than "facts".
