the band was ready to play the Auckland circuit, where they mesmerised their audiences with their edgy, heavily Hendrix influenced hard rock sound. The trio recorded three albums with Billy TK on guitar: Burning Up Years, Stoned Guitar and Pins In It, which made the band legendary in New Zealand. In 1970, Human Instinct played a three nights a week residency at the Bo Peep club, Durham Lane. One occasion they were joined by guest band The Game , who had been the 1970 Battle of the Bands Auckland Winners. Human Instinct played two nights at Hatchets, 24 Cook St, also supported on one night by The Game. In 1972, during a short tour of Australia Billy TK left Human Instinct after a series of disagreements on musical direction. He was replaced by Graeme Collins (Dedikation/Dragon). The group recorded three more albums before going into hiatus. Billy TK's Powerhouse In 1972 he formed a new band, Billy TK's Powerhouse, playing in Wellington with former Blackfeather drummer Steve Webb from Australia, guitarist John Bilderbeck from Wanganui and Gav Collinge on bass. When Webb and Bilderbeck left, Powerhouse shifted base to Palmerston North, recruiting Ara Mete on rhythm guitar, Jamie Tait-Jamieson on keyboards, Bud Hooper on drums, Arnold Tihema on congas and lead vocals and Mahia Blackmore on vocals and percussion. The band later also featured Neal Storey (ex-Dragon) and Peter Kellington. Powerhouse supported Black Sabbath, Split Enz, John Mayall, Sonny Terry and Brownie McGhee, UB40, Joe Satriani and the Neville Brothers in concert. Keyboardist Jamie Tait-Jamieson (founder of Biofarm Products Ltd.) left the group during this period, having given up full-time musicianship to run his family farm and marry his fiancée Catherine Rowland. Powerhouse disbanded in 1977. While they released no records during their career, an album's worth of unreleased 1972 studio recordings (all cover versions) were belatedly issued in 2009 as Move On Up. A live concert recorded in 1975 received a very limited vinyl release in 1990 as Life Beyond The Material Sky. Later work In April 1996, TK performed a song with Carlos Santana at an Auckland concert. He has worked with several bands including Dunedin Flying Nun Records band King Loser, with whom he recorded an album, and with hip hop artist DLT. He later played at several Human Instinct reunion gigs. In November 2008 TK unexpectedly joined former Powerhouse keyboardist Jamie Tait-Jamieson (now part of the
