Pure Music was the third and final album by jazz-rock fusion band Chase. The failure to sell the Ennea LP on a mass market forced Bill Chase to re-group several times and come up with a new musical approach; the result was Pure Music. Work on a 4th LP was in the works and during 1974 Chase had been performing a melodic flugelhorn piece called "Ode To A New England Jellyfish"; this tune was recorded and only missing Bill's solo section. Other selections never made it beyond the sketch stage.
