We no longer need to introduce the Cortex group and its leader Alain Mion! So here's the double single in 45rpm format from the “Inedit' 79” project, which came out of the drawers in 2006 and features recordings from 1979 and 1981 that were unpublished before 2006. The track “I Heard A Sigh” has been sampled by a number of hip-hop artists, while “Where Do You Come From” will not appear on the LP due out at the end of 2025.
