J.A.H.N.O. was born in the mountains of Auvergne, France. Introduced to music in his childhood by his mother, herself a pianist and organist, she teaches him the essentials of keyboard. At the age of 5, he goes to music school and begins trumpet for 5 years. Then, he tries saxophone, continuing musical theory. At age 15, after 5 years of saxophone, J.A.H.N.O decides to beat the barrels (normal when you live in the rue des caves (= cellarstreet).
In 1998, after exploring the drums, inspired by the rythms of Sly Dunbar, he falls in love with reggae drumming technique. At that time, he has lessons with Christophe Merzet, master of the Tambours d’Auvergne. In 2000, J.A.H.N.O. and some musicians from Clermont-Ferrand form the «Magwaman Riddim Section». This backing-band plays around the regions’ bars and parties during 3 years. They used to be support acts of U-ROY, BIG YOUTH & MAX ROMEO, ANTHONY B, SLY & ROBBIE, IMPROVISATORS DUB, ZENZILE a.o. The band splits in 2002, but will reborn under the same name with new electro-dub elements. From then on, J.A.H.N.O. pushes his own musical project of oldschool sounding dub forward. After many years of accumulating vintage studio material, J.A.H.N.O. builds his studio to work on his own productions.
There, he learns by himself on recording and mixing techniques. As well as his motherland an dits gastronomics products, he loves also tube circuits and tape for its fat, rich and round sound.
In 2004, he records « Singes Debout », a 4 titles EP with Sixto Freddo.
In 2008, jahno produces a solo album “Dubbin the cave” available on Plynt Records.
