Early Years: 1996 to 2001

Joe Quinteros and Sajahan Natkin met as teenagers in Amsterdam and started to DJ in local nightclubs.  But it was following a trip to Goa and India that the pair found their musical calling, immediately drawn to the sound of Goa and Psy-Trance.

On their return to Amsterdam they teamed up with Sebastian Claro and after releasing a couple of singles recorded their debut album under the name Growling Mad Scientists, or G.M.S.  ‘Chaos Laboratory’  (Hadshot Haheizar 1997) was pure Goa Trance / Psy-Trance, of the style that Paul Oakenfold had brought to mainstream European audiences a couple of years earlier..

By the time of their second album ‘The Growly Family’ (TIP Records 1998) GMS had started to develop a more distinctive style of their own. In addition to their now trademark whacky samples, their sound was more minimal and harder, in many ways beginning to pave the way for the rise of Full On a few years later.

In 1999 Claro left group but Quinteros and Natkin continued from their base in Ibiza (they had move there in 1997).   The following year Quinteros and Natkin set up Spun Records along with Seth Hoffman and Bradd Hosking.

Early Years: 2002 to present

It was with the launch of their fourth studio album ‘No Rules’ (Spirit Zone Recordings 2002) that GMS really started to break through.  In 'No Rules' their sound was incorporating most of the core elements of the emerging Israeli Full On sound.  The tempo of tracks was faster and the overall feel was more driving with driving bass lines and tight percussion. ‘No Rules’ included the track ‘Juice’ which with its incessant rolling bass line, hard house influenced riffs and distinctive lead hook became their most successful single track to date.

In 2004 GMS’s growing success was reflected in a number of their tracks being licensed to the Hollywood Denzel Washington-starring blockbuster ‘Man On Fire’. 

By the late nineties some of GSM’s momentum appeared to have slowed.  They released their last studio album to date in 2005: ‘Emergency Broadcast System’ (Spun Records 2005). In 2008 the pair left Spun Records and set up a new label Starbox Music to feature tracks from both GMS and their various side projects.

GMS came onto the scene just as Psy-Trance was beginning to lose direction.  They ended up straddling the Goa dominated nineties and the Full On era of the noughties, evolving their sound in the process and also themselves actually helping shape the transition of Psy-Trance as a whole.  GMS remain well regarded and respected within the Psy-Trance DJ and producer fraternity.

Joe Quinteros and Sajahan Natkin met in an Amsterdam coffee shop in the early teens. Joseph Quinteros played the drums from 11 to 17 years of age and also bass and guitar thank to the influence of his musician father.
