new info on band au fic! it's called perfect strangers in stoke.
Remus & Sirius were friends (met in private school but in the later years). They got really close but then had a horrible falling out when Sirius was starting the band. Remus only got invited back in through Lily (who is the keyboardist) at a party when she invited him.
Remus is the bassist, but when the band begins to get more popular, he becomes one of the more popular members due to him being very sexy and mysterious mostly because of his scars.
Sirius is SUPER jealous of Remus when he starts to get more popular because Sirius is the frontman and he should be the one getting popular.
Remus, however, is really cocky yet disgusted when he realises he's getting a lot of fans. On one hand, he doesn't like the attention, but on the other hand, Sirius being so obviously jealous is actually hilarious.
Relatively toxic Wolfstar to be frank. They kind of hate each other.
The Valkyries & Slytherin Skittles are in their own bands, but they're less popular and more underground. Sirius bashes them whenever they're around or being spoken of because "they got the idea from him", is what he says.
Sirius is overall very weird because he hates being rich but is also a complete prick to Remus, who was homeless for a while after Sirius completely dropped him and doesn't have much money. But Sirius wants to pretend to be poor (eg: faking a "lower-class" accent so people can't tell he's from a higher class family) yet is very insensitive to people who actually are impoverished. Remus detests him for this.
Lily is also in the Valkyries band, which is called Aphrodite & the Arrows. She sometimes plays for the Marauders band when Peter, who is the keyboardist normally, gets sick.
The Slytherin Skittles are called the Knockouts of the Snake House. (TIY that they're called Skittles not after the candy but after the game "Skittles" because the goal is to knock down the little like pin things and knocking down the pins is like knocking down lives and anyway they're dead and I think thats funny).
Marauders instruments!! Sirius: Singer + Electric Guitar. Remus: Bassist. James: Drummer. Peter: Keyboardist.
Sirius learnt basically all of the other instruments as well. In case he ever wants to do a weird solo rendition of any of the songs, he can do it pretty well. Trying to learn how to play them all at once (think that super cool Aaron Paulsen guy).
Everybody has at least one break down.
The band was together for seven years but was world-renowned for three.
Anyhow I'll come back if I think of anything else! I'll also be posting the summary I made for AO3 soon!
