 This was known as Supergroup I, but this line-up actually never performed together; dissolving before any live performances came to fruition.However, Frenreisz, Presser, and Laux from the supergroup decided to work together, and they formed Locomotiv GT with Frenreisz taking on the role of vocalist, and with new guitarist Tamás Barta, who had been part of "Youth Magazine's" next supergroup, in Budapest on April 6, 1971.József Laux and Gábor Presser had been members of Omega (which also featured Benkő and Kóbor from the original supergroup) up until this point; and consequently left Omega in order to form Locomotiv GT.
