He recorded alongside fellow Twisted Nerve artists Badly Drawn Boy and Andy Votel on several releases and played drums with two further bands, Misty Dixon and D.O.T.
Having heard Badly Drawn Boy's "EP1" he started taking his tapes to Andy Votel who then worked at Fat City Records.
Dakota Oak, his solo act, released Kaleidoscope, a 10" vinyl mini album in April 1999, which received positive reviews.
Meanwhile Tyack had gone from teaching to working in the call centre at Smile, the internet bank, which was a happier time for him, but a publishing deal allowed him to give up his job and concentrate on his music.
He began collaborating more, with Badly Drawn Boy on "Wrecking the Stage" and Mum and Dad on "Black Sabbath" in 2000, and then joining Misty Dixon, another Twisted Nerve act, initially to aid with four-track recording but eventually playing drums and piano and writing with Jane Weaver.
The mini LP that followed, David Tyack with Richard Tomlinson and Naomi Hart contained some new compositions, new arrangements of tracks from Am Deister, a cover of Townes Van Zandt's "Colorado Girl" and the traditional song "Rock Island Line" (which, unusually, Tyack sang), all recorded as live in a studio.
He played on Jane Weaver's mini-album Like an aspen leaf, released in May 2002, and recorded new music for the Twisted Nerve compilation Zoo.
Tyack was found dead on the island of Corsica in June 2004, nearly two years after being declared missing, having apparently fallen to his death.
