Any guitar slinger worth his or her salt can dust off Neil Young's "Helpless" or Buffalo Springfield's "For What It's Worth" and take a pretty good pass at singing those '60s chestnuts. But it takes some serious discipline and an intuitive sense of melody to pull off the multipart harmonies of Crosby, Stills, Nash & Young. Marrakesh Express steps up to the task of re-creating the biggest hits of the folk-rock supergroup by faithfully reproducing the look, feel and sound of a CSNY experience, even down to the band's hippie threads. Luckily, the group has the harmonies and licks to justify the tie-dye and bell-bottoms. Expect airings of the biggest hits ("Suite: Judy Blue Eyes"), late-period songs ("Southern Cross") and everything in between.
