Before playlists, streaming, and instant access to nearly every song ever recorded, there was the mighty 45. One little record could introduce you to a song, a band, even an entirely new genre. We carried them in cases, traded them with friends, played them to death on little bedroom record players and, if you were me, meticulously cataloged them in a handwritten binder. 😂 And then there was the greatest little mystery of all: the B-side. Two sides. One little record. A whole world of music waiting to be discovered.
