Since his first experiences playing with legendary drummer John Stevens in 1989, Ramanan has been a major presence on the London improvised music scene. Constantly exploring the boundaries between composition and improvisation as well as the sound possibilities of the trumpet, he has worked with Peter Brotzmann, Eddie Prevost, Evan Parker, Simon Fell, Marcio Mattos, Alex Ward, Alex Hawkins and Tony Marsh. 

Ramanan has been a conductor and stalwart of the London Improvisers Orchestra since its inception. 

He has two recordings on Emanem records (Shaken and Caesura); his latest record release and project is the free jazz tentet on Leo records. Ramanan also plays in the punk, funk, improv trio Vole - soon to be released on Babellabel.
