With multiple sold-out U.S. tours under its belt and hundreds of thousands of fans around the world, Leonid & Friends continues to astound its global audience with its unique ability in capturing the spirit, musicality, and fire of American supergroup Chicago.

And what is even more stunning is that Leonid & Friends, comprised of 11 of the finest musicians in Russia, Ukraine, Moldova, and Belarus, haven't seen Chicago perform live, yet replicates the band’s complex arrangements amazingly note for note.

Chicago has never been in Russia, and none of us have attended their concerts," said Leonid Vorobyev, a multi-instrumentalist who is the band’s leader. "We have only recordings and videos (to help us learn Chicago songs)."
