Marty O'Brien is a professional bassist who is originally from Rhode Island and currently based in Los Angeles. Having played bass for numerous touring acts as well as recording sessions for rock and pop artists plus various television and film scores, O'Brien has a discography that is, overall, somewhat diverse while also maintaining a solid background in the hard rock and metal music genres. His live credits include playing bass on tour for bands such as Disturbed, Tommy Lee, Static-X, Methods of Mayhem, Lita Ford, and many others. He has performed on three different Ozzfest tours, each time with a different band (Ozzfest's 1998, 2000, 2002). Also a busy session-bassist, most of this work taking place in his current home base of Los Angeles, O'Brien has recorded with numerous artists such as Celine Dion, Chris Cornell, Brian McKnight, Tommy Lee, Lindsay Lohan, Lita Ford and Kelly Clarkson; the later includes the number one single, Because of You from the Grammy award winning album titled Breakaway.
Born and raised in Pawtucket, Rhode Island, O'Brien started playing bass at the age of 13. By age 16, he had joined his first local rock band, and by 19, was playing local live shows in Providence, as well other cities along the east coast such as Boston and New York City.
Marty O'Brien's professional career began in 1998 when a local Providence, Rhode Island based band, Kilgore asked him to join their lineup as their new bassist. A few weeks after joining, the band embarked on the "Ozzfest 98" summer festival tour, where the band shared the stage with such bands as Ozzy Osbourne, Tool, Incubus, System of a Down, Limp Bizkit, and Motörhead. Next came a North American tour supporting Slayer and Fear Factory, then a European tour in the winter, supporting Fear Factory. In January 1999, vocalist Jay Berndt quit the band, which eventually led to the end of Kilgore.
Methods of Mayhem
In April 2000, Marty moved to Los Angeles, and just 3 weeks later was asked to audition for Tommy Lee 's new band Methods of Mayhem. Marty was offered the job the same day as the audition, and the band left for Europe 8 days later and spent the summer playing some of the biggest festivals across Europe. (Dynamo Open Air, Rock Am Ring, Rock Im Park, Glastonbury Festival). Next, the band spent the rest of the summer touring the U.S. on the "Ozzfest 2000" festival, sharing the main-stage with bands Ozzy Osbourne, Pantera, Godsmack, Static-X, Incubus, P.O.D., Queens of the Stone Age, and Disturbed.
In early 2001, the multi-platinum selling metal band Disturbed asked Marty to join them on tour after their bassist Steve "Fuzz" Kmak had broken his ankle in a fall from a fire-escape outside the band's rehearsal complex. Marty spent two months playing bass for Disturbed on an extensive tour throughout Europe, opening for Marilyn Manson.
In the summer of 2001, the multi-platinum selling band Static-X called upon Marty to fill-in on tour after their bassist Tony Campos had fractured his collar-bone in a motorcycle accident. After having only one rehearsal with the band, Marty toured with Static-X on the "Extreme Steel Tour" which also included the legendary pairing of the bands Pantera and Slayer. This would ultimately be Pantera's last tour ever.
Between 2002 and 2005, Tommy Lee recorded and released two solo albums. In 2002, "Never a Dull Moment" was released, on which Marty has a songwriting credit, and 2005's "Tommyland: The Ride". From 2002 to 2005, during the promotion of both those records, Marty played bass on both world tours and performed on several TV shows, including The Tonight Show with Jay Leno, Jimmy Kimmel Live!, The Ellen DeGeneres Show, The Celebrity Roast of Pamela Anderson, and a handful of European TV shows, including Top of the Pops.
In 2004, Marty chose to focus more on recording-sessions in Los Angeles. Over the next few years, Marty quickly accumulated an impressive resume of artists that he has recorded with, such as Celine Dion, Chris Cornell, Brian McKnight, Mýa, Tommy Lee, Lindsay Lohan, and Kelly Clarkson, including her number 1 single, "Because of You", on the grammy-award winning album, "Breakaway".
We Are the Fallen
In 2009 Marty became a member of the new band We Are the Fallen, along with former Evanescence members Ben Moody, Rocky Gray, and John Lecompt, featuring American Idol runner-up Carly Smithson on vocals. The band was launched on June 22, 2009 at a press conference in Hollywood, CA, and soon signed a deal with Universal Republic Records. Their debut album was released on May 11, 2010, and the band toured extensively throughout that year, supporting the band HIM, as well as playing many summer festivals in Europe such as Download Festival and Rock Am Ring.
In early 2012 Marty joined Lita Ford 's touring band. (Former guitarist for The Runaways). The band toured extensively in 2012 as the opening act for Def Leppard and continues to tour the world through 2013 in support of Lita's latest album, Living Like a Runaway. In Sept of 2013, Lita will release a new Live album on which Marty played bass, titled "The Bitch Is Back...Live".
