Miklós József "Jackie" Orszáczky (8 May 1948, Budapest, Hungary – 3 February 2008, Sydney, Australia) was a Hungarian-Australian musician, arranger, vocalist and record producer.

[1] During the Hungarian Revolution of 1956 the Orszaczky family hid in their cellar for a week and emerged to see their home with bullet ridden walls and the local streets with dead bodies of people run over by tanks.

[4] By August 1973 Jackie Orszaczky had returned to Australia and joined Bakery, an experimental progressive rock group which had already released two albums – he remained until the band broke up in February 1975.

[4][7] Soon after he used a studio band of Peter Jones on electric piano, Graham Morgan on drums and John Robinson on guitar (ex-Blackfeather), to record his debut solo album, Beramiada.

[4][7] In December that year, Beramiada was issued on the Real label and "featured accomplished progressive jazz-fusion in the vein of Weather Report, George Duke and Caravanserai-era Santana".

[4] He worked for Hines for four years and appeared on her debut album, Marcia Shines (October 1975) and its related singles including, "Fire and Rain" (May 1975), "From the Inside" and "I Just Don't Know What to Do with Myself".

[1][8] In 1987 Orszaczky formed Jump Back Jack with Linda Bacon on trumpet and vocals; Mike Bukowsky on trumpet; Mark Simmons on saxophone; James Greening on trombone; Phillip Campbell on drums (ex-Electric Pandas); Phil Colson on guitar and vocals; and Hamish Stewart on drums (Ayers Rock).

[4] In 1990 he founded The Godmothers with Chris Abrahams on keyboards and Greg Sheehan on drums; (Blackfeather, MacKenzie Theory, Richard Clapton Band).

[4] In August 1994 Orszaczky released his second solo album, Family Lore, backed by The Grandmasters which had a line-up of Abrahams with Arne Hanna on guitar (Whirlywirld, Max Q), Cathy Harley on piano, Tina Harrod on vocals, and Geoff Lundgren on synthesiser.

[9] He established a career as a leading musician in the front rank of much of the best jazz, soul, funk and rhythm & blues music created in Australia in the 1970s to the 2000s.
