Heldon's Live In Metz '77. Available here on LP.
Richard Pinhas, the founder of '70s legends Heldon, is one of France's best known experimental musicians and is a key figure in development of rock music fusing with electronic music. During the 1977 tour Heldon played 3 never released tracks. These titles have also never been recorded since and were thought to be lost forever. But luckily they were found recently. The sound is rough, but it's a rare document, so here's the chance to finally hear them.
LP - Standard LP.
