Brown was the principal songwriter for the 1960s baroque-pop group the Left Banke, writing their two biggest hits, "Walk Away Renee" and "Pretty Ballerina".

Internal band tensions saw Brown leave the Left Banke in late 1967, prior to the completion of their second record.

They were introduced by their fathers, Peter Buonconsiglio[7] and Harry Lookofsky, who had worked together as session violinists.

Brown left the band prior to the recording of Hot Chocolate's "Brother Louie", which became a No.

[5] Brown briefly reunited with the Left Banke at a New York performance in June 2013.
