Been listening to this dreamy chanson, "Lentement", by Bertrand Belin feat. Barbara Carlotti non-stop since yesterday yet took a serious peek at Bertrand Belinâs discography. I really love his voiceâIâm easily hooked on deep, velvet fog, golden gravel, baritone male singers. I find his musical approach is cool, too: slow paced and elegant songs structure. I like his city slick look as well.
