The band, set up in October 1972, was first called Classic XX, adopting the name Progresiv TM (being inspired by Locomotive GT) in April 1973.
The starting formula included vocalist Harry Coradini (real name Harald Kolbl, born February 20, 1944, in Timișoara), guitarist Ladislau Herdina, bassist Zoltan "Zoli" Kovacs, drummer Helmuth "Hely" Moszbruker, and keyboardist Ştefan Péntek.
In 1975, Kovacs was replaced by Ilie Stepan and the group received two new members: Mihai Farcas (drums, percussion) and Gheorghe Torz (flute).
In September 1975, Progresiv TM, composed by Coradini, Herdina, Stepan, Moszbrucker, Farcas, and Torz, released their first LP, Dreptul de a visa (The Right to Dream).
Coradini left the country, and Herdina returned to Timișoara, where he later re-established the group in 1983 with a hard rock sound instead of a heavy-prog one.
