The psychedelic trance group "Growling Mad Scientists" are based in Ibiza, Spain and regularly tour the world. Former members have been Amrit (2), who was mainly a DJ, but participated in some tracks during the 90ies, Sebastian Claro, who left the group after a two-year stint, and Yakov Biton from Israel, who left the group after the completion of Chaos Laboratory. G.M.S. began when "Riktam" and "Bansi" met in high school at age 14 in Amsterdam. Both were passionate about electronic music and the duo chose to leave school and seek their education in the club scene. Even though they were too young to legally enter a nightclub, Riktam and Bansi began spinning at clubs in Amsterdam. On most occasions, they had to be whisked into the building's side door to avoid scrutiny by the authorities. Amsterdam's club/rave scene was in its infancy In the early 90's and genres like gabber dominated the fledgling culture. Two years later, Riktam and Bansi traveled to Goa and experienced a musical epiphany. It was in Goa, India they started playing goa trance. While there, Riktam and Bansi deejayed at some of the wildest, most memorable parties of their young lives. After returning to Amsterdam, one of their friends had purchased some recording equipment. They started their production career and named themselves G.M.S. In 1997, they moved to Ibiza, Spain and in 2000, Riktam and Bansi formed Spun Records with partner Seth Hoffman. Josef Quinteros (Bansi) passed away on 19/06/2018 and GMS have become solo project of Shajahan Matkin (Riktam) since then.

There was a time when a group of very talented people joined forces and became known as Growling Mad Scientists, releasing amazing tunes such as "do androids dream of electric sheep", after some success and for no reason they decided to deprive the world from good music and began a conspiracy known as "full on" among other producers. Now they are the McDonalds of psytrance and are known as GMS since that name is more marketable.

Shame on thee.
