That bass work on Saturday In The Park is freakin' AMAZING. And after listening to I'm a Man (one of my favorite tunes ever) it confirms the bass player is a monster.
Man, those dudes are GOOD.
The bass player is Leonid Vorobyev. He is the band leader, conductor, arranger and producer.
I think he's amazing. The recordings sound so incredibly good.
And yes, his bass playing is incredible too.
