Final Fantasy XI online . All the expansions too . <| sep |> You should definitely watch it . The lead characters might remind you of KOn and it ' s about music , but the similarities stop there . The show is very story driven and has brilliant character development and interactions . It also the best music you ' ll ever get to hear in an anime , right from the OPs , the EDs and the music competitions and the art is godtier . The second season has a fully animated 8 minute band performance with perfect depiction of finger movements of every note of music played . You should watch this show just for that episode . Here is another super badass , spoiler free musical performance from last week ' s episode wrOCrchdoHQI ' m linking you this one because you ' ll have to watch the performance I mentioned in the second paragraph for yourself .
