He is a founding member of The Dictators, one of the original New York punk bands, in which he wrote nearly all of the songs, played bass guitar and keyboards, and sang backing vocals and occasional leads.

He has been involved with a variety of other musical projects, most notably the heavily Dictators-populated Manitoba's Wild Kingdom and Joey Ramone's first studio album, Don't Worry About Me.

[1][2] Shernoff's current projects include garage rock band The Masterplan, featuring members of The Fleshtones and the Waxing Poetics.

On March 24, 2012, Andy played the Reason Rally, the largest secular gathering in American history, on the National Mall in Washington DC.

The publication's contributors included famed rock critic Lester Bangs, who invited Andy to write for Creem magazine.

Lauded by Trouser Press as a "wickedly funny, brilliantly played and hopelessly naïve masterpiece of self-indulgent smartass rock'n'roll", the album nonetheless failed to connect with the general public at the time and Epic dropped the band.

Disillusioned, Shernoff left the Dictators for a short time and was replaced on bass by Mark "The Animal" Mendoza before returning to the band, on keyboards.

Shernoff's side project with the Waxing Poetics' Paul Johnson and Fleshtones Keith Streng and Bill Milhizer, the Master Plan, released its first album, Colossus of Destiny, in 2003.
