In the replies you can catch a new episode PBS Off Book titled "We ❤ Retro Media: Vinyl, VHS, Tapes & Film." With the increased interest of listening to music on vinyl and cassettes, I thought this video would definitely be worth your time.
Me, and a lot more people than you'd think. My band just released a cassette. And like the person above said Keep It Together and plenty of other labels release cassettes. It's an awesome and cheap to make format.
