The trio recorded the two albums HAT: Tokyo-Frankfurt-New York (CD, 1996) and HAT: DSP Holiday (CD, 1998). Only the first album was released on Atom™'s "Rather Interesting" label in 1995, before it then came out on Haruomi Hosono's "Daisy World Discs", soon to be followed by their second album in 1998. The "Rather Interesting" version, both differs in artwork and mastering from the japanese release. Both albums were recorded partly in Tetsu Inoue's studio in New York, Atom™'s studios in Frankfurt and later Santiago de Chile as well as in Haruomi Hosono's "Quiet Lodge" in Tokyo. For the recording session of "DSP Holiday" Haruomi Hosono managed to spend two very jet-lagged days in Santiago de Chile, yet most of the production was done by sending files and recordings back and forth between Tokyo, New York and Santiago/Frankfurt.
Both albums are no longer officially available.
