Hat Hut Records

Werner X. Uehlinger started the HatHut label in 1975 to release recordings by Joe McPhee and soon followed with albums by emerging avant-garde jazz musicians including Steve Lacy, David Murray, David S. Ware and Jimmy Lyons. The first releases on HatHut between 1975 and 1979 had alphabetic catalog numbers starting with A and ending with a triple LP Y/Z/Z making a total of twenty albums in the series.[6]

From 1980 to 1981, following the last alphabetic catalog number, HatHut releases had a written numeric catalog number followed by a bracketed "RO" code where the first digit of the code indicated a single ("1RO"), double ("2RO") or triple ("3RO") LP.[7] A total of 22 albums were released in this series.

From 1981 to 1983 Hathut released a series of seventeen albums on the hat MUSICS label.[8]

From 1981 to 1987 Hathut released a total of fifty-one albums in the initial hat ART LP series, many of which were packaged in fold-open cardboard box like sleeves which sometimes included postcards, additional 45rpm EPs, 7" singles, or single sided albums.[9]

Hathut began releasing compact discs on the hat ART label in 1988 with a 6000 series catalog numbers featuring new music and reissues of vinyl albums, sometimes with additional material. The series featured 201 releases and concluded in 1997 when the hatART label was replaced by two labels: hatOLOGY for jazz releases and hat(new)ART for classical music.[10]

From 1997 hatOLOGY has been the main label for HatHut releases releasing new recordings and reissues, occasionally edited or expanded, of music from the early HatHut catalogue.[11]
