HELIUM is an acoustic trio composed of Katy Vachon, Patrick Mercier and Roger Fontaine combining voices, guitars, U-Bass, ukuleles and percussion which revisits, in its own way and without pretension, songs from the 70s to today in several styles, ranging from Pop, to Country, including Retro and Rock. Although the three members and friends have known each other for more than 25 years and have already had joint musical projects, the trio HELIUM officially saw the light of day at the end of 2021.
