Tangerine Dream are unquestionably one of the most influential electronic groups of all time. Their music has made an immeasurable impact on ambient, new age, techno, trance, and progressive rock, as well as modern film-score composition. Founded as a psychedelic rock group in 1967 by Edgar Froese, the group pioneered the use of sequencers with classic albums like 1974's Phaedra and 1975's Rubycon, which proved to be commercially successful. They became prolific film composers, most notably scoring the 1983 blockbuster Risky Business. Subsequent albums such as 1985's Le Parc and 1988's Optical Race incorporated digital instrumentation, as well as shorter, more pop-oriented compositions than their earlier epics. Froese passed away in 2015, but a trio lineup continued to record and perform, remaining true to his vision. Expanding into a quartet, the group released Raum in 2022.
