Not sure if there are any Twenty One Pilots fans on this board (guessing probably not, as it seems like most people's music taste here is classic rock or metal), but man I am excited for their upcoming album. Not just for the music, but also completing a 4 album long, complex storyline.
I grew up in the 80's/90's and was a massive grunge fan which fortunately saved me from hair metal which has not aged well. For the longest time, Nine Inch Nails were my favorite band and I still like a lot of their stuff.
I didn't really know of Twenty One Pilots when they were at their peak of popularity around 2015 or so as I haven't listened to regular radio in probably 2 decades - having switched to XM Radio and then Spotify. Really got into them a few years back though and eventually learned about their "lore", which is a storyline that will come to a conclusion with their upcoming album/videos. The 4-minute video below that they released a few days ago sums up much of the storyline, though you can go down rabbit holes for hours on the details of this storyline and clues that they've (often cryptically) released to fans over the years.
Anyway, curious to hear if any other bands have done something along these lines? I know bands have had concept albums before, but haven't heard of an ongoing storyline to this extent played out over a series of albums.
