Canadian rockers Three Days Grace have been a fixture in the third millennium music scene with their energetic brand of alternative metal and hard rock, racking up numerous awards and multi-platinum sales along the way. Originally going by the name Groundswell during the early 1990s, singer/guitarist Adam Gontier, bassist Brad Walst and drummer Neil Sanderson reinvented themselves as Three Days Grace in 2003, then signed with Jive Records, and released their eponymous debut that same year. An instant success, the album yielded one of the decade’s biggest mainstream rock hits in ‘(I Hate) Everything About You’ and threw the band (now a quartet, following the recruitment of lead guitarist Barry Stock) into a three year touring and promotional roller coaster. By the time they paused long enough to begin work on a sophomore album, Three Days Grace channeled their mixed feelings about the entire experience (as well as Gontier’s personal struggles with addiction and recovery) into 2006’s ‘One-X,’ which once again marched its way to Platinum and allowed the band to tour relentlessly with bands like Seether an Breaking Benjamin. Two more commercially successful albums have followed in 2009’s ‘Life Starts Now’ and 2012’s ‘Transit of Venus,’ but the latter was followed by the troubling news of Gontier’s resignation from the group to pursue other musical endeavors. His replacement was singer/guitarist Matt Walst, brother of bassist Brad and a member of fellow Canadian hard rockers My Darkest Days, who made his recorded debut with Three Days Grace on the digital single, ‘Painkiller,’ released on April 1, 2014.
