Pat Thomas and Dominic Lash have been improvising together since 2001, but their very first duo took place in 2021, and is documented on the album New Oxford Brevity. Although most of their work together sees Lash play double bass, in the duo Lash plays electric guitar, and Thomas eschews electronics to focus on piano.
New Oxford Brevity has been described as "text book improvising of a very high standard" (All About Jazz), as "piano glissandi, guitar buzzes and squalling flanges as energetic as a Cecil Taylor/Derek Bailey duet" (Jazzword), and as both "taking our breath away" and "making our nerves bristle", thereby "setting the record straight concerning the expressiveness of freely improvised music" (orynx-improvandsounds).
