In cooler times – this past March – South by Southwest barely registered one of its myriad weather events. Temperatures dropped 25 degrees between 8pm and 2am, so having gone on late at 1am, German synth pioneers Tangerine Dream played well past bar time. Icy, gale-force winds afterward couldn’t erase 90 minutes having intersected with music history.: Born to 1967 Berlin, the electronic trio blazed a waveform pathway unequaled by fellow kosmische and krautrock contemporaries Kraftwerk, Neu!, and Can. That same Me Decade, founder Edgar Froese began scoring films and by the Seventies soundtracked German TV movies. William Friedkin’s searing 1977 thriller Sorcerer bristled Tangerine Dream’s synthy slither and led to further work on cinematic classics Thief, Risky Business, Near Dark, etc.: “The score for Grand Theft Auto V was another challenge because the game itself influences the mix depending on the player’s position inside the game,” writes Thorsten Quaeschning, to whom Froese bequeathed the group, which now includes violinist Hoshiko Yamane and keyboardist Paul Frick. “That was a very interesting way of composing a soundtrack."
