3. Elton John and Leon Russell, The Union
Two rock giants, one largely forgotten, rekindle a friendship and make music that ranks with their best. Producer T Bone Burnett delivers his most spectacular production in memory, filled with shining steel guitar, chortling brass and gospel-time choirs. Ultimately, it's Russell's voice that shines brightest, drawing on the entire history of American popular music in its canny, vulnerable, knowing croon.
