Mike Stern played with MB at so many albums and lives including Steps Ahead.
He plays in some MB's albums, and also, he invited MB at his recordings.
In such albums, MB always plays remarkable solos.
This tune has a charactristic chromatic A-melody, as the title.
MB makes solo under this suspended mode.
BTW, At Steps Ahead, there were 3 "Mike"s --- MB, Stern, Mainieri.
How did they call each other ?
