There’s been some, admittedly minor, bands releasing new albums on cassette. I saw a guy walk out of the bookstore the other day with a stack of them. They have many new and old fans. My first music purchases were on cassette, even in the late 90s. CDs were for rich kids.
I used to laugh at that line from 30 Rock that “technology is cyclical.” Nostalgia is a hell of a drug.
