Edling started his musical career in the band Trilogy, then under the name of Toxic, as a singer together with
Ian Haugland (later the drummer of
Europe) in 1979. He then played in a band named Witchcraft but left in 1981 and formed Nemesis in 1982. Before the Candlemass official releases, Edling also handled vocal duties in addition to playing bass. After the departure of
Messiah Marcolin, Candlemass became his solo project, until the band reformed in 2002. In 1994, when Candlemass fell apart, Leif had started the band
Abstrakt Algebra with
Mats Levén on vocals and
Mike Wead on guitar. The band met with limited success and disbanded after one album. In 2002, he founded another doom metal band, named
Krux, also with Mats Levén on vocals, and in 2013 founded
Avatarium with Marcus Jidell on guitar and Jidell's wife, Jennie-Ann Smith on vocals. From 2014 to 2019, Edling was unable to tour with both Candlemass and Avatarium due to unspecified health problems, believed to be
chronic fatigue syndrome. A variety of replacement members were used, including
Grave/
Entombed bassist
Jörgen Sandström. == Discography ==
