Never really clicked with those first four Ash Ra Tempel albums. But when Manuel Göttsching starts to get deeper into technology - delays and other FX - on 1975's Inventions for Electric Guitar he develops this uniquely blissed and glistered flow-motion. Rippling synths and sequencer-style pitter-patter pulses enter the sound picture with those underrated late '70s albums like New Age of Earth and Blackouts - heading towards the revelation of E2-E4.
My absolute favorite out of everything Göttsching did, though, is this gorgeous glory: "Wall of Sound", off The Private Tapes Vol. 2. Jump to 39.51 in the clip below (although the whole album is well worth your time). Recorded in 1979, "Wall of Sound" is another step toward E2-E4 featuring sublime shaft-of-sunlight-through-cigarette-smoke guitar-playing.
