He has created his own unique sound by seemlessly integrating multiple genres (Americana, Ambient, Krautrock, Post-rock, Indie Rock, Country/Folk).
Impermanence (2014, Three Fish Music) has been described like this (translated from indiestar.es): 'If we talked about a new work that was made by the typical type of semi-known American songwriter in the small “alternative” world who visits Spain each year to blind us with his genius, and who would receive praise and adherence everywhere for his rare warmth, feeling, originality and variety of intent, that is what this is and what comes out of “Impermanence”, fourteen songs for music lovers that go beyond music to what music could be or become, a work of art.In this new work Greg offers a bit more “aggression” to his introspective approach, within his style of the “quiet man” surrounded by infinite pedals. And, to make you take interest in the disc, the name that comes to the top of my mind is (although each song could have its own) … Beck?'
Greg is also the bassist of Tripulante y Crucero and has played in Marcus Doo & the Secret Family along with collaborations with Territoire and Nine Stories. He prefers to co-produce his music with the musical magician, David Sergeant.
