A native New Orleanian and recent New Yorker, Ethan is a working composer, lyricist, and music director currently in Asheville, North Carolina.

"Andersen is a smart writer. He knows how to write an incredible song." (Theater in the Now). Ethan's songs are "nimble across a variety of styles, from musical scenes and frothy uptempo to vampy torch and searing heartbreak." (Talkin' Broadway). 

In 2014, Andersen's original musical, HeadVoice, premiered at Elon University and, in 2015, was selected and produced by the New York Musical Festival. "Complete with rich harmonies and a book, music, and lyrics by Ethan Andersen, this show hits home in a charming, truthful way." (Times Square Chronicles).

In 2016, Ethan's children's musical, Rootabaga Express!, premiered at Flat Rock Playhouse and is produced every summer at the Carl Sandburg Home National Historic Site. YOUlogy, a musical Ethan wrote with Charlie Johnson, received an NYC industry reading May 2018 starring Lianah Sta. Ana and Conor Ryan.

Ethan is a proud member of the BMI Lehman Engel Musical Theatre Workshop, ASCAP, and the Dramatists Guild.

As a music director, Andersen was MD/Conductor of the Saturday Night Fever national tour, as well as MD/Conductor of Elon University's Music Theatre program, one of the top MT programs in the country.
