Amar joined Godspeed You! Black Emperor around the time of its debut album, F♯ A♯ ∞. He, with Mauro Pezzente, plays the electric bass in the group. However, when playing with Thee Silver Mt. Zion Memorial Orchestra & Tra-La-La Band or Black Ox Orkestar, he can most often be found using the double bass. He was also once found playing violin on the EP The "Pretty Little Lightning Paw" E.P.
Amar is also a singer for Thee Silver Mt. Zion Memorial Orchestra & Tra-La-La Band, which shares vocals with all of its band members.
Along with Howard Bilerman, Efrim Menuck and Radwan Moumneh, Amar owns and operates the Hotel2Tango. Once a living space, it is now a professional recording studio, practice area, and live performance venue. Offering its facilities for almost anyone, Amar will sometimes take up the role of record producer for band sessions.
Amar also dabbles in the jazz and improvisational music scene, and studies with Jacques Beaudoin of the Montreal Symphony Orchestra, one of the most prominent orchestras in the world.
In 2006, Amar, with Efrim Menuck and Sophie Trudeau, assisted in the recording of Carla Bozulich's first release for Constellation, Evangelista.
