While in Great Speckled Bird, who was managed by Albert Grossman (manager for Janis Joplin, Bob Dylan, and founder of Bearsville Studios in Woodstock, New York), Kalmusky played on many records as a session musician with the likes of Jerry Reed, Amos Garrett, Todd Rundgren and many others. It has been said that nobody will ever know all of the records Kalmusky played on during this time as Grossman was not a huge fan of giving credit to session musicians at Bearsville Studios, but this was also a regular industry practice at the time.
