Adam Montez Guerilla (born November 5, 1977) is a Dominican American musician and songwriter who is well known for founding the experimental metal quartet, Adam and Pals, alongside rhythm guitarist and sampler Terrance Luther; all of this went underway in 2005. He was the second lead guitarist to play in Osmosis, for he contributed to the band's first two studio albums. Guerilla was eventually replaced by Shawn Lorelei.
In the spring of 2013, however, the band announced that Lorelei decided to leave permanently, so they welcomed Adam back in the Osmosis family with open arms.
