This is a gold mine. TD’s early albums — Electronic Meditation, Atem, Alpha Centauri, and especially Zeit — were brilliant, but it was when they signed with Virgin and released Phaedra, Rubycon, and Stratosfear that they became a shockingly commercial prospect and built the career they’ve sustained ever since, even outlasting founding member Edgar Froese to cruise the endless spaceways as a brand/institution. This 16-CD box includes those three albums, plus Cyclone, Force Majeure and the live Ricochet and Encore, as well as a wealth of alternate mixes, outtakes, and previously unreleased material — four complete concerts from 1974 and 1975, and an entire shelved studio album, Oedipus Tyrannus. The albums have almost all been remastered and sound amazing, the analog synths in particular possessing an eerie beauty that’s never been matched by later generations of electronic music technology. The live albums feature lengthy improvisations that take one even deeper into the endless void. The sheer volume of music here (not to mention the super-deluxe packaging) makes the physical object a diehards-only prospect, but it’s also weirdly the ideal entry point for newcomers to TD.
