In highschool I was introduced to Rush by our band director (well, we were all introduced to them forcibly
). He has good taste though, it's been my favorite band ever since. As a musician I find them hard to not like, as professional as they are with their music. Always crisp and clean music and very unique songs with very thoughtful (and often deep, and/or political) lyrics. Also they're immortal, because despite their age none of them have died and they still go on tour.
Also I give a little nod to OK Go every now and then because as rarely as I listen to their new music, I'm often surprised that it continues to actually be kind of good. Lastly, I have to give a nod to Abingdon Boys School because years later I still find their anime openings getting stuck in my head for no reason.
