My favorite rock band in the 80s (at least the second half of the decade, when I had an opinion on such things) was unquestionably Iron Maiden. They were a heavy metal band, with all of the associated imagery and attitude, but they were also, secretly, sort of a prog-rock band, if that style of music hadn't declined precipitously in popularity in the mid-late 70s.
They had Bruce Dickinson with his Conan the Barbarian haircut bellowing like a Viking out of a Wagner opera, twin lead guitarists Dave Murray and Adrian Smith trading off face-melting solos, leather and spikes like Judas Priest, an elaborately theatrical stage set with pyrotechnics and a giant papier-mache monster head, violent and gory imagery featuring Eddie the zombie on their album covers, and their song "The Number of the Beast" got them accused of being Satanists. They were very loud and very aggressive and seemed very dangerous and very cool to my pre-teen self.
All of the "hoods" in my middle-school, the mostly-poor kids who had long hair and smoked, loved Iron Maiden, right alongside KISS and AC/DC and Def Leppard and Ozzy Osbourne (Metallica hadn't really caught on in our area yet). They were always surprised that I liked that stuff too, and it was how I bonded with that group, even though the teachers didn't like it and thought I was being led down the wrong path (about which I loved proving them wrong and shaming their close-mindedness).
Because what those teachers didn't understand (and, to be honest, I'm not sure many of the kids understood either) was that although they looked and sounded like other metal bands, Iron Maiden were smarter and more sophisticated - they had lyrics about history and literature (and even did a 13-minute-long version of Samuel Taylor Coleridge's "Rime of the Ancient Mariner") and they were seemingly just as influenced by 70s prog-rock bands like Genesis and Jethro Tull as they were by Black Sabbath, Deep Purple, and Thin Lizzy. This was, effectively, music for nerds that happened to also appeal to the cool and tough kids. As a nerd-by-inclination who also wanted to hang out with the cool kids, it was right up my alley, almost like it had been tailor-made for me.
The 80s were Iron Maiden's decade. The first, self-titled, album was released in 1980, and they put out just about an album a year through the rest of the decade, including The Number of the Beast in 1982 (the first album with Bruce Dickinson; their first hit and the one that got them pegged as Satanists), Piece of Mind in 1983 (where the full "classic era" lineup was finally in place), Live After Death in 1985 (their first live album, recorded in Long Beach, CA (I now know some folks a few years older than me who were in attendance), and the first of their albums I owned), and Seventh Son of a Seventh Son in 1988 (a full-on prog-rock-style concept album; I was totally obsessed by this album, wore out two different cassette tapes by listening to them so much, and - naturally - tried to adapt its story into a D&D campaign).
In the 90s they released some sub-par albums and had some lineup changes and I lost interest and moved on to other types of music - like punk and grunge and "alternative" stuff that the older high-school kids were into. From what I understand around the turn of the century Iron Maiden got the classic lineup back together and are still regularly releasing new albums and touring the world and playing to ridiculously large crowds and are probably bigger and more popular now than they were in the 80s, but I never got back into it. I did upgrade a few of my cassettes to CDs and still pull them out for a nostalgic listen now and then, though, and it instantly takes me back to being in seventh grade, listening to those albums on endless-repeat. I like it better that way.
