Rossi was raised in Toronto, Ontario, Canada. He formed and fronted two bands; the first was Cleavage with brothers Jon and Bill Jameson. The Toronto-based band won the "Best Canadian Unsigned Band" award at the 2000 NXNE Music Festival in Toronto. In 2004, Rossi entered into a publishing deal with EMI Music Canada. After acquiring this deal, Rossi worked with producer Dave Tyson in Los Angeles and later recorded demos with producer Gavin Brown. In 2005, Rossi partnered with guitarist Dominic Cifarelli and drummer Maxx Zinno along with his longtime friend, Jay Cianfrini, to form a band in Montreal called Rise Electric. Rossi and two of his colleagues, Mike Fox and Gavin Brown, were winners in the 2006 People's Voice International Songwriting Competition for their song, "Drive". It gained third place honors in the Top 40/Pop category and landed seventh place in the overall competition.
''Rock Star: Supernova''
While Rise Electric was on hiatus in the spring of 2006, Rossi competed in Los Angeles, California, on the television show , as an audition for a new band composed of Tommy Lee, Jason Newsted, and Gilby Clarke. His selection as lead singer of Rock Star Supernova earned Rossi a tour of the U.S., Canada, Australia, and New Zealand in early 2007. One of his songs, "Headspin", was included on the band's album which earned platinum status in Canada.
After Rock Star Supernova
Rossi returned to Los Angeles to begin work on his own solo acoustic act. The Love and Lust EP was released June 2007. He toured across the U.S. and Canada during the summer, accompanied by keyboard player, Lou Dawson.
Stars Down
In 2008, Rossi debuted his next project Stars Down. The band consisted of Rossi, German Briseño of Vim Furor, with occasional appearances by Lou Dawson, and guitars and drums with various musicians. The album was originally scheduled to be released in 2009 but Rossi has stated it may never see the light of day due to his own dissatisfaction with its quality. However, in 2011 Lukas released a flash drive that contained his back catalog, including the previously unreleased album "Mood Swings".
Switchblade Glory
On April 15, 2011, a debut album was released which featured Rossi as lead vocals under the band named Switchblade Glory. The album was engineered and co-produced by Andy Johns. The band features Kenny Aronoff on drums, Steve Polin on guitar and Greg Mauro on bass. Producers are Gary Hoey and Steve Polin. Lyrics and melodies by Rossi.
In 2012 Rossi teamed up with Evanescence co-founder/lead guitarist Ben Moody to form a new project called The Halo Method. In September 2012, the band released an introductory track, "Beauty is the Beast", for an online interview with Revolver Magazine and performed their debut show aboard the rock and roll cruise, Shiprocked, in November. In 2013, the band released an lyric video of "Toxic" and "Reset", an EP which features four songs: "Toxic", "Beauty Is The Beast", "Porcelain" and "Crutch". The EP is available as a free download at The Halo Method Soundcloud. Later in the year, the band appeared at Rock The River, a benefit festival for Angel on My Shoulder. Following their second appearance on Shiprocked in late January 2014, The Examiner described the sound of the band: "The Halo Method rounded out the night on the main deck stage with their hard synth-fused rock show at top notch. The Halo Method features former members of Evanescence, and other well known projects, so these are not novice performers to the live stage. They produce hard rock energy with full emotion in one 'rocking fell swoop'. This band combines it all into one hell of a sound and show: elements of hard rock, goth, alternative metal, industrial, and pop with a great presence from a great band and the voice of Lukas Rossi." The band released a video for "The Last Astronaut" as performed aboard the ship.
King City
Since 2016, Rossi has been working with Neil Sanderson of Three Days Grace on a project called King City.

Lukas performed live at the 2006 Gemini awards, appeared on and won the CBS television series Rock Star: Supernova, as well as appearing on The Ellen DeGeneres Show, Live with Regis and Kelly, Jimmy Kimmel Live!, Entertainment Tonight, The Howard Stern Show, and ET Canada.
