Madder Lake are an Australian progressive rock band formed in Melbourne in 1968 as San Sebastian. They were one of the first bands signed to the Michael Gudinski co-owned Mushroom Records which released their debut single, "Goodbye Lollypop" in February 1973, followed by the album Stillpoint in August. This contained their most recognisable single, "12lb Toothbrush". Their second album Butterfly Farm was released in April 1974, they left Mushroom after their last single, "I Get High" appeared in July 1976. A compilation album The Best of Madder Lake was released by Mushroom Records in 1978. History 1968-1976: The peak years San Sebastian were a part-time rock band formed by Swinburne Institute of Technology (now Swinburne University of Technology, Hawthorn campus) Graphic Design students in 1968, including Kerry McKenna on bass guitar and Brendan Mason on guitar. By 1969 the line-up was McKenna, Mason, Mick Fettes on vocals, Jac Kreemers on drums and John McKinnon on keyboards, they were playing cover versions for the pub circuit. Original material was introduced and, by late 1970, band members were leaving their tertiary studies to fulfil their bookings. With a repertoire of progressive, psychedelic, blues music they changed their name, in early 1971, to Madder Lake—madder lake is a crimson-coloured water-based dye (alizarin) mixed with alum and used in painting. The Melbourne-based line-up of Fettes, Kreemers, Mason, McKenna and McKinnon were picked up by Michael Gudinski's booking agency, Consolidated Rock. Madder Lake were influenced by British progressive rock acts, Family, Traffic and King Crimson. They were the opening act at the inaugural Sunbury Pop Festival in January 1972. As their popularity increased, they were one of the first bands signed to the Gudinski co-owned Mushroom Records in late 1972. By 1973 they were a headlining act at the 1973 Sunbury Pop Festival and Mushroom Records' first release was their debut single, "Goodbye Lollipop", in February. The single peaked at No. 15 in Melbourne and made the Australian singles Top 40. Mushroom Records' first album release was the ambitious triple-live, The Great Australian Rock Festival - Sunbury 1973, which was released in early April, and included two Madder Lake tracks. Madder Lake's debut album, Stillpoint followed in August, which peaked at No. 13 on the Australian albums chart, it spawned their most recognised single, "12lb Toothbrush", written by band members Fettes, Kreemers, McKenna and McKinnon. McKinnon had been replaced on keyboards by Andy Cowan by
