His early experience scoring movies came from his project with "Sounds Like Australia" (1987), a wildlife movie that required him to rework the sounds of Australian wildlife into music. In the following years, Lasar worked with Hans Zimmer on the movie, "Days of Thunder", starring Tom Cruise. Shortly after, Lasar was asked to help with composing an album with Seal, a new artist at the time. That album earned a Grammy nomination. Lasar released his first solo album in 1991 and now has over 30 solo albums as well as a collection of collaborative projects. Mars' music has been featured in shows such as Conviction (NBC), 24 (Fox), America's Got Talent, Extreme Makeover, The Bachelor, and others.
