It is composed of lead singer and guitarist Nathan Peyton, bassist and brother background vocalist Chad Peyton, lead guitarist Luke LeDoux, and drummer Frank Goerz.  Their first full-length album, "Into Existence", was released as Rides Again on 2 October 2007.  The first single, "Wonder Why", was produced by Gavin Brown (known for producing other Canadian bands including Billy Talent and Three Days Grace).  Videos and singles followed for Infected and It's Too Late, which received play on MuchMoreMusic.  "Infected" became a top 10 modern rock hit in Canada.  The band has toured with Theory of a Deadman, Social Code, The Trews and Hedley, Yellowcard among others.  A few years before "Into the Existence", Rides Again was known for their hit song "Geeze Louise", a pop rock song popular among young teens.  The band was incorporated with Vodoo Records at this time, playing across southern Ontario.  At this time the original drummer and cousin of Nathan and Chad, Bradley Christiansen, was in the band, but had left later on to pursue other career options.  2007 seemed to be the year for the striving Canadian band having their music videos published on Much Music, and Much More Music as well as radio stations across Canada.  In mid-2009, Mike McElroy resigned as Rides Again drummer to pursue other importances.  After Mike left they asked drummer and musician Kelly Voelkel to join the band, Kelly performed all of the drums and percussion on Hollowick's upcoming album.  In July 2009 Kelly left to pursue more professional endeavours.  Friend Anthony Moreino and former Rides Again merchandise guy filled in on drums for a short time for Hollowick, until new drummer Frank Goerz was found.  With Goerz now behind the drum kit, there's a new level of explosive energy never felt before for Hollowick.
