Hailing from France, Hellebore was the collective effort of Jean Cael (Bass, Crumar and Vocals), Alain Casari (Saxophone, Clarinet, Flute and Vocals), Antoine Gindt (Guitar and Crumar), Daniel Koskowitz (Drums, Percussion, and Vocals) and Denis Tagu (Piano, Organ, Guitars and Vocals). Stylistically Hellebores' sound is almost impossible to categorise. Formed and composing music after the initial heady days of 'Rock In Opposition' (RIO), when RIO music was anything but flourishing, they held firmly to the roots of many earlier RIO.
