Gregory Raimo, known professionally as GR, was born in 1977 in Grenoble, located in the French Alps.
Beginning in his early twenties during the late 1990s, he explored various creative fields, including painting, writing, and music.
In 2005, he established the band Gunslingers (Massacre-rock deviant inquisitors) alongside Antoine Hadjioannou on drums and Matthieu Canaguier on bass, both of whom were founding members of the band Aluk Todolo. Gunslingers was characterized as a power trio that merged the sonic impact of the Velvet Underground’s “guitar amp tape” with the noise and frenetic energy of Les Rallizes Denudes at their most anarchic. Their sound has been likened to the raw expressions of the Stooges in Funhouse and the bluesless mutant garage style of the Monks in Black Monk Time. Following the release of their album, Julian Cope remarked, “NO MORE INVENTION is nothing less than the sum total of every move culled from every essential No Wave, Post Punk, Free Rock statement thus far spewed forth onto vinyl and CD…Inject the whole sticky mess up the puckered ass of the current Indie Scene and STAND WELL BACK !!!… future record libraries without a copy of this LP will risk being declassified and shut down instantly.”
With Gunslingers, GR recorded three albums and one EP: No More Invention (2008, released on the German label World in Sound), Manifesto Zero (2010, World in Sound), Supreme Asphalt Doser (recorded in 2012 and released on Opaque Dynamo, Feeding Tube Records, and Cardinal Fuzz in 2022), and Massacre-Rock Deviant Inquisitors (recorded in 2012 and released in 2013 on Les Disques Blasphematoires Du Palatin and Riot Season). The band primarily toured the United States, performing around 75 shows, with only a few rare live appearances in France and Europe, possibly due to their distinctive style.
Under the moniker GR, which he initially adopted as a painter in the 1990s and early 2000s, Gregory Raimo released five solo albums: Xperiments From Within The Tentacular (2007, LDBDP), GR & Full-Blown Expansion (2009, LDBDP; 2010, World in Sound), A Reverse Age (2012, Mexican Summer), Propel Tension On Polyester Base (2016, Opaque Dynamo), and The GR Record Head (2020, Opaque Dynamo & Cardinal Fuzz). His solo work encompasses a wide range of styles, including composed and free-form experimentation across genres such as free rock, krautrock, space rock, psychedelic rock, no wave, protopunk, garage punk, and minimalism. Notably, GR performs all instruments on his albums, drawing comparisons to artists like Kim Fowley and Alexander Skip Spence, while demonstrating a persistent focus on the art of sound recording.
In 2007, he collaborated with psychedelic legend Michael Yonkers on the album The High Speed Recording Complex, which presented a raw and powerful blend of psychedelic and lo-fi noise (CD-2007/LDBDP; LP-2010/B.F.E).
In 2018, GR released Hôpital De La Conception / The Electric Rockin’ Chair, a project for solo guitar on his Opaque Dynamo label, which was reissued in 2019 by Feeding Tube Records and Cardinal Fuzz. The performance was described in the liner notes as “a real mind-distorter for all zealots of primitive electric guitar fury… a tantalizing charge of impenetrable origin, deeply infused in savage fire.” Chris Stigliano from Blog To Comm characterized Hôpital De La Conception as “BRAVE ENOUGH TO ACTUALLY CHANNEL THE FERAL ELEMENTS OF THE VELVET UNDERGROUND INTO THEIR OWN DECADENT DNA,” adding that it possessed “that ‘Sister Ray’ hard-nosed Velvets drive which kicks up the spirit and makes you PROUD that you are a mammal and alive in the here and now if this is any indication of what the future shall bring us in music.”
In 2020, GR's tape music experiments were released under the title Sensor/Spook / Collapse & Rise At The Air Mass (2020, Opaque Dynamo), featuring an improvised exploration in two parts that combined techniques of tape music, concrete music, and spacey electronic music.
Additionally, GR operates the label and mail order service Opaque Dynamo, which he has managed since 2016, previously known as Les Disques Blasphematoires Du Palatin from 2006 to 2016.
