On 1998's The Boy with the Arab Strap, Campbell delivered her first lead vocal, "Is It Wicked Not to Care?" With her ethereal voice and striking, Jean Seberg-inspired looks, it was inevitable that she earned much attention from fans and media alike, and in the spring of 1999 she released her first full-length solo project, the Gentle Waves' The Green Fields of Foreverland.... A second and final Gentle Waves release, Swansong for You, followed a year later, but Campbell nevertheless remained a full-time member of Belle & Sebastian through mid-2002, co-writing the Top 20 U.K. hit "Legal Man" before finally exiting just prior to the release of Ghost of Yesterday, a collection of Billie Holiday covers recorded in collaboration with jazz musician Bill Wells.
After 2003's Amorino, Campbell kept a low profile for several years, finally resurfacing in the spring of 2006 with Ballad of the Broken Seas, a collection of duets with former Screaming Trees frontman Mark Lanegan. The two again collaborated on 2008's Sunday at Devil Dirt and 2010's Hawk. ~ Jason Ankeny
