Marianne Faithfull: Before The Poison
With 1999's Vagabond Ways, Marianne Faithfull started turning her albums into guest-star-studded affairs, bringing in everyone from Elton John to Roger Waters to Beck to Billy Corgan to co-write songs and provide musical support. She's one of the few singers who could do this without worrying about losing her own personality in the process. Even if her voice hadn't aged into such a distinctive cracked cabaret croon, no one comes with as much history as Faithfull: She could probably turn a Lil Jon composition into a master class in dogged perseverance.
