The renowned French horn player known as Brother Ah (aka Robert Northern) is one of the most prolific and respected musicians in the history of jazz music, with a recorded output spanning more than 30 years.

Following a classical French horn education, he emerged in the late '50s and established himself as a skilled session musician.

He recorded well into the '60s with some of the most illustrious names in jazz, including Donald Byrd, Dizzy Gillespie, John Coltrane, Thelonious Monk, Miles Davis, and Sun Ra.

In 1969, Ah formed his own group, the Musical Sound Awareness Ensemble, and released several works under his own name from 1974 onward.

His first solo recording, Sound Awareness was released on the Strata East label in 1972.

By this time, Ah had recorded extensively with the Sun Ra Arkestra and his solo work continued the boundary-pushing approaches he explored with that ensemble.

Consisting of two side-length tracks, "Beyond Yourself (The Midnight Confession)", and "L ove Piece", the album features notable appearances by percussionist Max Roach and the M'Boom Re:percussion Ensemble, as well as a 90-piece vocal choir.
