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.

In 1975, Ah released his second LP, Move Ever Onward on his own label, Divine Records. A more straightforward affair, the record infused Indian, Japanese and African folk music elements into more traditional jazz structures than Ah's debut LP.

Of its eight tracks, four include vocals by the artists Dara, Aiisha, Kwesi Gilbert Northern and Ayida Tengemana.

The instrumental tracks provide more colorful moments, such as the cacophonous percussion on "Boundless Rhythm" and the hypnotic kora and koto notes on "Enthusiasm" and "Celestial Strings".
