I'd say listen to their first album (A Fever You Can't Sweat Out) and their third and fourth albums (Vices and Virtues/Too Weird To Live Too Rare To Die)

I'm not saying you have to memorize all those songs, but I've been to a P!ATD concert before and they usually play those albums the most, so I suggest listening to them just so when you go there's some familiar sound

dont really memorize songs from pretty odd since brendon is salty and rarely plays any of those (i think he removed it entirely??) but their first album and doab are the ones you should memorize since they play those most

okay thanks guys
