Aydin Hasirci has been putting out house records as ATFC since the late nineties. the letters stand for aydin the funki chile, a nod to jimi hendrix rather than to the country. between 1997 and 2002 he worked the counter at uptown records in soho, when house still moved on vinyl, next to seamus haji and tim deluxe.

the other name is onephatdeeva, and that is the one that got him on national radio. In and Out of My Life came out on defected on 18 october 1999 and peaked at number 11 on the official singles chart, credited to onephatdeeva. it also went to number one on the official dance singles chart. he runs an imprint under the same name.

the follow-ups charted too. Bad Habit, with lisa millett, reached number 17 on the official singles chart in september 2000 and number three on the dance chart. Sleep Talk, again with millett, hit number 33 on the singles chart in february 2002 and went to number one on the dance chart. Spreadlove took number three on the dance chart in april 2006.

defected gave him a volume of its house masters series on 19 october 2009, shared with David Penn. the two of them later made Hipcats together for armada subjekt, out 26 february 2018. Chris Lake has remixed him as well, taking on Tell U Y with yasmeen.

the biggest thing in the modern half of the catalogue is U Got Me, released on armada on 12 june 2020. he also cut Spirit of House with gene farris for toolroom on 28 february 2020.

no upcoming bookings are published for him on RA, songkick, bandsintown or skiddle. the records have not stopped, though. defected put out a clüb de combat remix of Bad Habit on 23 may 2025, and Speaker, made with seamus haji and k.c flightt, arrived on big love music on 19 june 2026, which puts him back alongside the man he worked that soho counter with.
