The group released two albums, Evolution (1969) – after which Tim Gaze replaced Zytnik on lead guitar – and Goolutionites and the Real People (1970) before disbanding in 1972.
[1][3][5] Late that year Peter Barron replaced Connell on bass guitar and the group, now based in Sydney, changed their name to Tamam Shud.
[1][2][3] The line-up of Barron, Bjerre, Davidson and Zytnik played "acid-surf progressive rock" influenced by "psychedelic sounds of Cream, The Jimi Hendrix Experience, Pink Floyd, Eric Burdon and The (New) Animals, plus the San Francisco stylings of The Grateful Dead" according to Australian musicologist, Ian McFarlane.
[1] They became a popular attraction at local discothèques and "head" venues, and, like their contemporaries Tully, they often performed in association with a Sydney film and light show collective, Ubu.
[1][2] In January 1970 Tamam Shud performed at Australia's first outdoor rock festival, the Pilgrimage for Pop, held at Ourimbah, 78 km north of Sydney.
[3][7][8] During early 1970 they recorded their second LP, the environmentally-themed, Goolutionites and the Real People (October), but in June both Davidson and Gaze left to form another progressive rock group, Kahvas Jute.
[9] McFarlane described Tamam Shud's second album as their "masterpiece, an ambitious concept suite, a carefully crafted song cycle of cosmic enlightenment and cascading acid-rock.
During 1971 Tamam Shud's line-up expanded by the addition of Larry Duryea (ex Heart'n'Soul) on percussion; they were regularly augmented on stage by multi-instrumentalist, Richard Lockwood (ex-Tully), and a jazz pianist, Bobby Gebert.
The group was invited to contribute music for the soundtrack for the Alby Falzon surf movie Morning of the Earth (1971) and Falzon initially wanted Tamam Shud to provide all the music, but after G. Wayne Thomas took over as producer, other artists were added, and Tamam Shud's involvement was eventually reduced to just three tracks - the instrumental track "Bali Waters" (featuring Lockwood on flute), and the songs "Sea The Swells" and "First Things First".
Shud continued to tour through the first half of 1972, playing the Mulwala Festival in April, and making more trips to Melbourne in May and July, but in August 1972 Bjerre announced the imminent breakup of the group, which was attributed to management problems, "fear of musical stagnation" and the band's frustration at not being able to record another LP.
Tamam Shud continues to record and perform occasionally to the present, with the core lineup of Bjerre, Gaze and Macara (Barron has now retired from playing), and they have released two albums of new original material.
