Without doubt, the recordings of Tangerine Dream have made the greatest impact on the widest variety of instrumental music during the 1980s and '90s, ranging from the most atmospheric new age and space music to the harshest abrasions of electronic dance. Founded in 1967 by Edgar Froese in Berlin, the group has progressed through a full three dozen lineups (Froese being the only continuous member with staying power) and four distinct stages of development: the experimentalist minimalism of the late '60s and early '70s; stark sequencer trance during the mid- to late '70s, the group's most influential period; an organic form of instrumental music on their frequent film and studio work during the 1980s; and, finally, a more propulsive dance style, which showed Tangerine Dream with a sound quite similar to their electronic inheritors in the field of dance music.
contemporary American acid rock (the Grateful Dead, Jefferson Airplane), and played around Berlin at various student events. The lineup lasted only two years, and by 1969 Froese had recruited wind player Conrad Schnitzler and drummer Klaus Schulze. One of the trio's early rehearsals, not originally intended for release, became the first Tangerine Dream LP when Germany's Ohr Records issued Electronic Meditation in June 1970. The LP was a playground for obtuse music-making -- keyboards, several standard instruments, and a variety of household objects were recorded and filtered through several effects processors, creating a sparse, experimentalist atmosphere.
Both Schulze and Schnitzler left for solo careers later in 1970, and Froese replaced them the following year with drummer Christopher Franke and organist Steve Schroeder. When Schroeder left a year later, Tangerine Dream gained its most stable lineup core when organist Peter Baumann joined the fold. The trio of Froese, Franke, and Baumann would continue until Baumann's departure in 1977, and even then, Froese and Franke would compose the spine of the group for an additional decade.
