DAVID CROSBY, who turned 77 this month, has experienced a late career resurgence unlike almost any other in the history of rock & roll. Becca Stevens, Michael League and Michelle Willis backed Crosby on his tour in support of 2016’s acclaimed Lighthouse album, and BrooklynVegan said of the quartet’s NYC show at Town Hall, “they also clearly help him sound great. Crosby’s voice has aged wonderfully, but you’d have to assume the younger singers’ harmonies are part of what made everything sound so rich last night. This project reflects the collaboration with that amazing group."
