[2] The album, and in particular its ninth track "Huit Octobre 1971", has gained prominence since the nineties due to its frequency of being sampled in hip-hop music by artists like MF DOOM, Lupe Fiasco, and Tyler, the Creator.

Jeff Huttner, while considered a founding member, was replaced by bass player Jean Grevet for Troupeau Bleu due to "prior obligations in the United States".

[4] Opera Mundi referred to the album as a combination of soul, funk, bossa nova, and psychedelic rock and considered it a cult classic due to its unique arrangements and rhythms.

[4] Online music critic Gino Sorcinelli lauded Troupeau Bleu's "distinctive sound", stating that "All the drum hits are crisp as fuck, every piano and organ sequence is impeccable, the basslines sit perfectly in the pocket and complement each composition, and Mireille Dalbray's vocals are unbelievable...

CBS News wrote that " [Troupeau Bleu]'s mix of psychedelic atmospheres, jazzy grooves built around Fender Rhodes electric piano, earthy funk and Brazilian samba achieved a special chemistry that would resonate with a future generation of hip-hop producers.

The band's newfound interest led to Mion gathering new members for Cortex in 2009, embarking on tours in the United Kingdom and the rest of Europe, and reissuing old projects while releasing new material.

[9] By 2022, Cortex made several stops in the United States thanks to logistical support from Ali Shaheed Muhammad (a former member of A Tribe Called Quest), Adrian Younge, and their label Jazz Is Dead.

[4] In the twenty-first century, many artists have continued to sample from Troupeau Bleu including Tyler, the Creator; Rick Ross; Lupe Fiasco; Flying Lotus; Wiz Khalifa; Baby Money; Logic; Wu-Tang Clan; and others.
