Formed in 1972 as a quintet, Dzyan recorded their self-titled debut album after only two months and released it on Aronda, a small Bad Homburg label owned by producer Günther Müller. The original line-up, which never performed live, broke up after a few months. Bassist Reinhard Karwatky soon formed a trio that took the band's name. Karwatky, guitarist Eddy Marron and drummer Peter Giger signed a contract with Bacillus/Bellaphon, Peter Hauke (Omega, Nektar, Jeronimo, etc.) produced and Dieter Dierks was the studio engineer. On Time Machine (1973), the first album for Bacillus, Dzyan plays virtuoso jazz-rock that occasionally, especially on the 18-minute title track, reminds one of John McLaughlin's Mahavishnu Orchestra. At the same time, the trio does not lack a certain herbaceous rawness. On their second Bacillus album, Electric Silence (1974), the trio celebrates their Kraut-Jazzrock to perfection. In its review of the album, the leading German jazz magazine Jazz Podium concluded that Electric Silence would establish Dzyan as 'probably the best German band' in the field of jazz rock. Achim Breiling of the online magazine Babyblaue Seiten said: 'Electric Silence is certainly one of the strangest, but also one of the most impressive and independent of what has been produced in Germany in the border area between jazz and rock.'
