Tom Middleton (born 18 August 1971)[1] is a British electronic recording artist, sound designer, composer, music producer, remixer and DJ.

A classically trained pianist and cellist, Middleton worked in the early 1990s with Richard D. James[3] (with whom he shares the same birthdate),[4] co-producing "En-Trance to Exit" on the Analogue Bubblebath EP for Mighty Force Records.

The label name later changed to Universal Language Productions and launched a sub-label, Heard, then became E3 before ceasing operations.

In 2007, Middleton abandoned the AMBA moniker, while still focusing on the ambient genre fusing classical traditions with electronica, featuring orchestral, choral and electro acoustic arrangements.
