Tolman, 52, managed the solo careers of CSN since 1985 after working as a tour manager for Stephen Stills and his band.

He also played guitar with Stills’ band and wrote, performed and produced with CSN. Tolman recently built an extreme sports management company, which he later sold, that included Winston Cup Champion Tony Stewart as a client.

All three members of CSN have expressed their condolences to their friend.

Graham Nash, reached at his home in Hawaii, said, “My heart is broken about the untimely death of my dear friend. I am so sad. He was a great, sensitive, caring and funny man. I will miss him for the rest of my life.”

Speaking from his home in central California, David Crosby commented, “Gerry was a good friend and he worked diligently and did a great job at managing Crosby, Stills & Nash. He was a part of this family for many years. We’ll miss him. My heart goes out to his family.”

Stephen Stills added, “Gerry was my rock, my protector and my best friend. He helped me do my art without being distracted by the slings and arrows of our crazy and wonderful business. I doubt I will meet his like again. I offer my condolences to his family and his friends, who number in the hundreds. I believe that ultimately, this will pull us all together.”

In lieu of flowers, Tolman’s family has asked donations be sent in his name to The International House of Blues Foundation, 6255 Sunset Blvd. 18th Fl., Los Angeles, CA, 90028.
