Amazon.comDouble Trouble without Stevie Ray Vaughan? Drummer Chris Layton and bassist Tommy Shannon get by with a little help from their friends, on an album of musical depth that will surprise skeptics and delight fans. Amid the varied shades of blue, highlights find the ace rhythm section reuniting with former Arc Angels bandmates Charlie Sexton and Doyle Bramhall II, Storyville singer Malford Milligan, and Stevie's brother, Jimmie Vaughan. There are passing-the-torch contributions from Jonny Lang, Kenny Wayne Shepherd, and Susan Tedeschi (the latter two on a thunderous revival of Led Zeppelin's "Rock and Roll"). But it's Bramhall's power-trio transformation of Muddy Waters's "She's Alright" that evokes the strongest memories of Stevie. The album ends in expansively sophisticated fashion, with Dr. John, guitarist Willie Nelson, and a string section on "Baby, There's No One Like You," one of the four songs cowritten by Layton and Shannon. --Don McLeese
