Martin and drummer Scott Mercado set out to start a band in 1990. Candlebox was formed in 1991 after guitarist Peter Klett and bassist Bardi Martin joined them. They gained a Billboard 200 top 10 hit in 1993 with their self-titled debut album, released by Maverick Records. The album's success was largely due to the single "Far Behind," a song written about two of Martin's friends who suffered heroin overdoses, including Andrew Wood of Malfunkshun and Mother Love Bone. The single reached number 18 on the US Hot 100 and was a top 10 hit in both the US Modern Rock and US Mainstream Rock charts. Candlebox released two more albums in the 1990s, but following several line-up changes and diminishing commercial success, the group broke up in an apparent attempt to be released from the Maverick label. Maverick considered Martin the sole remaining member of Candlebox and demanded a fourth studio album before finally terminating his contract in 2000. As a result, he would no longer receive album sale royalties while the other band members would. As of April 2011 Kevin has started receiving his royalties for all 3 Candlebox records. Following Candlebox's demise, Martin became lead vocalist for the band The Hiwatts. The group recorded the albumThe Possibility of Being in 2002 and began touring in early 2003. In late 2005, Martin was asked to rejoin Candlebox to promote their The Best of Candlebox compilation. The band subsequently signed with the Silent Majority Group label and began working on a new album. In 2007, Martin recorded vocals with label mates Tantric for the song "The One" from their album, The End Begins. The new Candlebox album, Into the Sun, was released in 2008 and was promoted by an extensive tour. In 2009 Martin was invited by three former members of the band Live to form The Gracious Few, a supergroup which also includes Sean Hennesy, a member of the Hiwatts who had also joined the re-formed Candlebox as rhythm guitarist for their live shows. The Gracious Few released their self-titled debut album in September 2010 and toured the US and Europe into 2011 to promote it. In 2014, Martin formed a side project with Sevendust drummer Morgan Rose called Le Projet.
