Russ quietly made his mark on the pop rock world in the 1970s. Still at it today I'm thinking.
Heck, I was listening to Nash/Crosby debut LP from early 1970s today and loved the drumming. Look on the record sleeve (yes, as in vinyl!) and sure enough Russ is all over it. Worked with James Taylor and probably a ton of other easy rock, California type artists of the time period (Jackson Browne?)... Definitely my type of drummer.
