Matty was smoking a joint in his studio, after his bandmates had left, when he heard someone walking in the nearby lot. His new studio neighbour, he hoped she wouldn't make noises since he wasn't in a good mood: at all. The new 1975's new album was coming out slower than expected, the radios and labels were pushing them to finish the project, so his nerves were tight as fuck.
The girl gets inside and starts to play her electric guitar in an angry way, like she wanted to let her feelings out thru music. Matty understood that, he also did it sometimes (it was how most of his best band's song were created) bur right now, that angry sound was annoying him a lot.
He kicks the wall that separated them "Can one smoke a joint in peace?!" he yells, running a hand thru his curls and taking a huge drag. His shirt was halfway unbuttoned and his tattoos were exposed.
He hears some mumbling and the girls starts to play harder. Oh, she wanted a challenge. Matty grabs his coat and goes in the hallway to bang at her stupid door.
