After a long battle with leukemia, Michael Brecker died last January at age 57. During his darkest moments, his spirits were lifted by doing what he enjoyed doing most, playing jazz.

Those closest to Michael, his collaborators on his final album , saw firsthand the toll the disease was taking on their dedicated bandleader. Miraculously, Brecker rose above the physical rigors of the studio and committed himself fully to completing the album.
