King Q4


Bertrand Groussard, aka King Q4, studied percussion at the Conservatoire of Saint Germain en Laye and he learned analog and digital recording techniques at EMC.

In 2000, he released one of the first French « electronica » albums, on the label Clapping Music, created especially for the occasion. He performed many times in France. He joined the group Encre and played drums for 4 years with them, touring in Europe. In 2006, Matt Elliott (Ici d’Ailleurs) hired him for his European tour, where they played at the Primavera Festival in Barcelona.
At the same moment, he took part of the art collective Section Amour, with whom he participated in a 12-hour concert of improvised music, « Je ne suis pas un artiste » by Geisha Fontaine and Pierre Cottereau. In 2010, he released the EP « Love Buzz » on Help Me Records.

And, in 2011, he founded J&Y with Laurencina Lam, whom he met in the group Pokett, where he presided on the drums. J&Y released two cassettes on the Chicago label Plustapes and a substantial discography on Bandcamp. They toured in the US, opening for the group Disappears, as well as in France, where they also toured with Beak> at the Temps Machine in Tours.

Soon after this, he devoted himself to video art, making music videos for his own groups and for his friends (Yeti Lane, E+…). King Q4 composed the music for Damien Gonzalesʼ short film, Il y a une guerre. King Q4ʼs music has also been used in commercials for the Olympics in 2012, HTC, Airbus as well as in more experimental films, some of which can be found on

Always innovating, King Q4 has founded Fingerlab, a company specialized in apps, and has supervised music-creation apps like Multipong, Rockmate, and Dm1, a drum machine that received an Apple Design Award in 2012.

In 2013, King Q4 composed and performed the contemporary dance show d’après une histoire vraie by Christian Rizzo, a piece for 2 drums and 8 dancers. And he mixed the music record of the show. This show was a real success with more than 150 performances around the world. Since 2021, he has collaborated with Massimo Fusco to create the audio capsules of SOUND BODIES and SOUND BODIES FOR KIDS.
