IIRC, came out around the same time as Edgar Winter: Frankenstein.
Back a few years .... Buffalo Sprngfield: For What it's Worth
Their best, IMHO.
Buffalo Springfield - Bluebird
About the same time. A bit of jazziness mixed with classic Ozzy and Iommi's guitar innovation.
I always liked Edgar and Johnny both, and saw each many times.
I recently read Johnny ‘s biography, and it was very interesting.
Edgar has been collaborating with some jazz artists as of late, and what a smooth sax.
