Johnny Nicholas has spent a lifetime soaking up the flavor of such vibrant music scenes as Chicago, Southwest Louisiana, and Texas (which he’s called home now for 45 years). While he is primarily thought of as a blues legend and gifted storyteller, his music is full-spectrum Americana — a rich gumbo of blues, Southwest Louisiana soul and Texas swing and honky tonk. His 2018 release “Too Many Bad Habits” reissue project and double vinyl package received a 2019 Grammy Nomination.
