I just finished reading "Indigo Overture" by Rikki_Oko, and really love it. It's not the band part of it, but I love the Spuffy dynamic and how they develop, and their individual characterizations. I also like the ensemble feel of the fic, giving the other characters time to shine. The only other fic I know that seems to have these qualities is "Blue Horizons" by Kantayra, although it's a little too fluffy for me. Help with recs! Preferably AH.
