The group was always more technoish and darker than their fellow friends Etnica. Filippo always went for a deep dark vibe while Francesco opted for the psychedelia. The guys have 2 nicknames they use in the scene: Francesco D'Amato featured in many tracks with G.M.S. as Franco Rossi, while Filippo uses the alias of Gino or Fleps. The nickname of Francesco was given to him in Brasil (when he spent a whole season DJing) as everyone called him Franco or Rossi because his hair is red (Rossi = Red in italian).
