Possibilities

Alicia Keys, Peter Gabriel and Yo-Yo Ma are among the artists whose busy schedules kept them from appearing on Herbie Hancock's aptly titled new album, "Possibilities," but the legendary jazz pianist isn't complaining.

Eager to explore new vistas, he has teamed with an array of young talents – including Joss Stone, John Mayer, Christina Aguilera, Raul Midon and Damien Rice – and such long-established stars as Annie Lennox, Sting, Paul Simon and Carlos Santana.

Other guests include ex-Phish guitarist Trey Anastasio, blues-rock upstart Jonny Lang and singers Angelique Kidjo and Lisa Hannigan........
