I heard Tom Sawyer on a friends stereo in 1981 as a H.S. Freshman and was hooked. They’re still on my playlist.
They first came on my radar in 6th or 7th grade when a classmate played “2112” while we were both in his parents’ basement. That would be around 1975 IIRC. At the time I didn’t think much of them.
The song that got my attention was released as a single that the AM rock stations here played to death in 1981: “Subdivisions” https://www.youtube.com/watch?v=V7_fdU7kUBI
