and recording music with a band he formed called Grand Luxx, featuring his former Mattox Creed band mates, guitarist Dan Bartley and drummer Hardy Mattox. Singer Matt Knabe, who had previously performed in a band called Project Simon, later joined and the newly formed quartet began recording songs. Marshall stated, "I'd say our music is rock, but it's very eclectic, and I think it can reach a wide audience. We have a little bit of alternative and some hard-rocking guitar riffs too. And Matt brings in some pop flair because his influences were bands in that genre." He also stated that with Grand Luxx, he had "kind of moved to a different role" and did more work on the production side. By July 2001, the band, having played a few shows, had six songs written with initial plans to record an album that fall. Some of Grand Luxx's original songs include "Stagnant" and "Insomniac's Dream." Also during this time, Marshall was in a band called Head Heavy with vocalist Maceo Morris, Dan Bartley and James Thatcher. The band completed a full length recording at Marshall's home studio but it was never formally released to the public. In 2012, Marshall joined Mark Tremonti's solo band Tremonti but due to personal reasons he left the project and was replaced by Wolfgang Van Halen in September 2012. Personal life Marshall attended Choctawhatchee Senior High School (1988–1991), Tallahassee Community College (1991–1993), and Florida State University (1993–1995), where he graduated with a bachelor's degree in interior design.
