The last album as Kluster, and the last with Conrad Schnitzler a part of the lineup, Eruption includes 50 minutes of "Elektroakustische Musik" recorded live in 1971. Closer to avant-garde and noise than space, it shows the influence of Schnitzler on early Kluster material with forbidding violin lines, heavily distorted organ, and an assortment of tape effects leading the way for several minimalist guitar workouts. Schnitzler himself reissued the album in 1997 through his Plate Lunch label.
