Self employed musician, guitarist, singer, composer and producer from Utrecht. 

Coma Kick was founded in 2007 and is based in Warren, Michigan U.S.A. The name of the band was inspired by a Dillinger Escape Plan Lyric. The five members, Ryan Spooner (bass guitar), Kevin O’Leary (drums), Tom O’Leary (guitar, backup-vocals), Matt Mariotto (lead vocals) and Dave Goodman (lead guitar), all have backgrounds in different local bands in the Metro Detroit area.

The band’s sound could be best described as straightforward rock sprinkled with progressive tendances. Each member has wide ranging tastes and brings to the table many interesting ideas. Anything from Helmet, Failure, The Life and Times, The Melvins, Hum, Mastodon and Faith No More to Porcupine Tree, Dredg and Rush; the band never tries to limit itself. Coma Kick’s aim is to make music which is complex, yet accessible; sonically driven, textural and dynamic. The band keeps integrity and passion for craft at the heart of what it does.

Mad Cow was a Alt/Grunge Band out of Metro Detroit during the mid 90's.
This was the first band for all four members in Mad Cow.  Formed in 1996 by friends and brothers. There was never an alternate line up of players for the band,  (one and done).

Megatron was an Alt/Metal outfit from the suburbs of Metro-Detroit from 1998 to 2001. 
The band featured members from a previous local band called Mad Cow.  Megatron had a new guitar player (Chris Eib) and all new songs written by the four members.  After playing around the area for some time, the band decided to expand the sound by adding a fifth member.  In 2000 Megatron added Rob Negron ( from 69 Octane) to the role of Vocalist, which allowed Tom O'Leary to focus more on guitar. The band played around the state and eventually recorded a 5 song EP with Rob. In 2001, the band disbanded due to natural causes.

Select was a band with a mix of rock/alternative/metal/hardcore/reggae influences that emerged from the Metro-Detroit band scene.
The original line up recorded a demo and one EP, totaling 8 songs. Select played around the state of Michigan to spread the music. After a couple of years the band would have to find a new bassist after Jack Henry left the group after the recording of the EP.  Kazia Nilsson would be the new fourth member of Select. He brought a funky playing style and a youthful outlook that gelled with the band's sound and culture.  Select went on to record a 3-Song Demo with Kazia. This time they recorded it largely with out outside help. The drums were recorded by the same people and at the same place as the other sessions, but the rest of this demo was recorded, mixed, mastered by Matt and Tom. The band disbanded in 2006.
