Ahh, the hipsters.
At first I thought they were kind of weird (Oh wow, a Captain Beefhart album!) but RDavidson is right, they're putting their spin on visiting "my" era which would be the late 1960s - late 1970s.
Then I had to pretend to grow up.
Back on topic, yes, it is the hipsters who are behind the cassette resurgence. They're cheap, it's not digital and they're small enough to hide in your wretched man bun (ha, ha).
