you guys like American Football?  one of their songs was on Ashley's playlist
I saw them live a couple years ago and even met Mike Kinsella briefly
they suddenly got back together in 2014 after 15 years to everyone's shock and made a 2nd album.  this was like my equivalent of Eagles getting back together.
so the moral of the story is it's never out of question for an artist to suddenly reappear out of the blue
