I have to say, I've found this episode kind of haunting in the couple of days since I've seen it. I realize that's most likely because of my previous familiarity with the Lawrence band, and the parallels between the real-life band and the plot of the episode--ie, the concept of siblings in a band, the fact that Clyde played the fictional version of himself, the use of one of their real songs, and the real-life sister Gracie's voice being used as the singing voice of the fictional sister. Anyway, it all combined to make the whole thing stick with me, and seem sort of melancholy!
One last piece of trivia: one of the things that Annie said about Elliot early on was that he preferred writing music at night. The real-life band actually has a song about that, and an interesting music video, in that it was filmed in one continuous long shot between sunset and sunrise, never breaking once. It's obviously sped up in many parts. LOL. But, at any rate, it's worth watching. 😄
