Tangerine Dream is a German electronic music band founded in 1967 by Edgar Froese. The group has seen many personnel changes over the years, with Froese the only constant member until his death in January 2015. The best-known lineup of the group was its mid-1970s trio of Froese, Christopher Franke, and Peter Baumann. In 1979, Johannes Schmoelling replaced Baumann until his own departure in 1985. This lineup was notable for composing many movie soundtracks. Since Froese's death in 2015, the group has been under the leadership of Thorsten Quaeschning. Quaeschning is Froese's chosen successor and is currently the longest-serving band member, having joined in 2005. Quaeschning is currently joined by violinist Hoshiko Yamane who joined in 2011 and Paul Frick who joined in 2020. Prior to this Quaeschning and Yamane performed with Ulrich Schnauss from 2014 to 2020. Schnauss only played two shows with Froese in November 2014 before Froese's passing.
