In 1970 he, along with John White, Hugh Shrapnel and Alec Hill, formed the Promenade Theatre Orchestra. After its disbandment in 1973 White and he continued as a duo. A pianist and percussionist as well as a composer, Hobbs has performed with a large number of individuals - Gavin Bryars, Michael Nyman, Steve Reich, John Tilbury, and Christian Wolff among others - and has written music for a large variety of ensembles and situations.

Amy on the Beach
(by the composer himself)
Amy on the Beach is a systemic treatment of the piano miniature By the Still Waters by Amy Beach. The piece is played twice, the first time using a pattern based on the number thirteen, which allows certain notes of the original to be played but not others. On the second iteration another part is added to the first, played one octave lower, and using an expanding and contracting pattern based on the numbers fourteen to twenty-two. This is a “covert” system; it is not intended to be followed by the listener, but is instead a way of filtering the notes of the original in a way which is outside my personal choice.
