foundational work within Greek rock. In 1979, he and other Greek rock musicians established the Artist's Company but never released an album. One of the songs produced during this time, Clown, Sidiropoulos' first song in English, later appeared on his 1985 album Zorba the Freak. In 1982, he again ran into trouble with censorship, this time with his album En Lefko, in which three of his songs ("I", "Adergraoud Me Stras", and "Istati Stigmi") were heavily censored due to references to drug use and other behaviors Minos EMI deemed anti-social. In 1980, he helped establish Oi Aprosarmostoi, who he continued to play with until his death in 1990. Posthumous releases In 1991, Oi Aprosarmostoi released Ante ke kali tichi maghes, an album with the same name as one of Sidiropoulos' earlier songs. It featured unreleased recordings of Sidiropoulos as well as tracks by other artists. The title could be interpreted as "so long, folks." The following year, Ta blues tou prigipa (The Blues of the Prince) was released, containing Sidiropoulos' experimental combinations of blues and rebetiko recorded between 1979-1981. En Archí in o Lógos (1994) had recordings from 1978-1989, spoken word, and fragments of an interview with ET2. The EP Day After Day (2001) was released by Minos EMI in collaboration with composer Michael Karras, who stumbled upon recordings of Sidiropoulos, Bourboulia, and bouzouki player Thanassis Polykandriotis from 1973. Acting Sidiropoulos had a brief acting career, with appearances including writer and director Andreas Thomopoulos' films Aldevaran (1975) and O Asymvivastos (1979); director Eugenia Fakinou's play In Kurdistan (1977) at Theatro Kava in Athens; and in the TV show Oikogeneia Zardi (The Zardis Family; 1983). Aldevaran was screened only at the Thessaloniki International Film Festival. He performed the songs in O Asymvivastos. Personal life and death In 1990, Sidiropoulos began experiencing paralysis in his arm, which doctors diagnosed as left plexus arm paralysis. He took a break from live performances after the diagnosis and the death of his mother. That summer, he went to rehab in Naxos for his prolonged heroin use, a topic he touched on many times in his music. On 6 December, he fell into a heroin-induced coma at a friend's house in Neos Kosmos and died in transit to the hospital after suffering a heart attack caused by the overdose. He is buried in the Kokkinos Milos Cemetery in Nea Filadelfeia. Sidiropoulos collaborated and was romantically involved
