This seems like a good time to link back to this chart I made last year about the setting of Band Vs. Band. In brief, if you don’t feel like clicking: it’s set in the present, not the past…but in a stylized alternate world where certain technology just didn’t advance. Physical format music is all records and tapes — no CDs, no computer stuff.
Also, just in case: did you miss the last page, which came out pretty late in the week (my fault)?
