Oleg does a great job on tenor here. Playing a Guardala mouthpiece, like Brecker.
I debuted my Guardala at the 1986 Savannah Jazz Festival.
Randy, the older brother, became famous as an original member of the group Blood, Sweat & Tears. He appeared on their debut album Child Is Father to the Man in 1968.
So this is a cover song of the original by the Brecker Brothers, called East River and it is being performed by a group of people from Russia calling themselves Leonid & Friends.
Thanks for the heads up on the new tune. I saw them last year in Phoenix - great players!
