The band was formed in 1993 by Jason Rockman, Kevin Jardine and Avrum Nadigel, in the midst of the “grunge” explosion. They were highly influenced by this particular sound early on. The original line-up also included Patrick Francis, and Lenny Vartanian. In 1995, the bass guitarist Francis and the drummer Vartanian were replaced by Frank Salvaggio and Robert Urbani respectively, beginning a new, heavier metal direction for the band.
At that time, the Canadian music scene had yet to embrace nu/alternative metal music, so Salvaggio and Urbani decided to make a six-day trip by Greyhound bus from Montreal to Los Angeles, the center of alternative metal, to begin the process of making in-roads, contacts and securing showcases for the band. After a year filled with showcases the band secured a record deal through Ozzy and Sharon Osbourne’s Divine Recordings which released their full-length album, Inches from the Mainline, in 2000.
The band also toured Ozzfest in 2000, and made an appearance on the SnoCore Tour. The album sold approximately 70,000 copies in the US.
After Divine Recordings lost their distribution deal with EMI’s Priority Records, the band was left without a label and returned to Montreal. Salvaggio once again returned to Los Angeles with the goal of securing another record deal. With the help of producers Jason Slater and Troy Van Leeuwen, a contract was signed with Bieler Bros. Records. Their second major album, Metafour, was released in 2003.
In March 2004, Rockman, the vocalist, left the band, prompting Slaves on Dope to disband. Salvaggio and Urbani are now part of the band Anew Revolution, with the ex-Unlocovocalist Joey Duenas. Jardine has become a producer in Montreal (Uplift Recording Studio), as well as forming his own band called The Monarchy (Disbanded).
In 2006, the band’s independent release One Good Turn Deserves Another was re-issued through Just A Minute Records. In 2009, Rockman and Jardine reformed Slaves on Dope and are now[when?] recording their third studio album. In a recent[when?] webisode, the band announced the name of the album to be Over the Influence. It was announced on webisode 18 that the recording had finished with 17 tracks. Rockman then[when?] said in a video on the band’s Facebook page that the album would be released in spring 2011.
In October 2011, it was announced that Slaves on Dope had signed to THC:Music/Rocket Science Ventures, the new label of the Corporate Punishment Records President, and early Slaves on Dope manager Thom Hazaert, who would release Over the Influence worldwide in spring 2012. They also announced the release of a digital-only EP, Careless Coma, in November 2011.
