Assuming whoever's reading this doesn't know anything but I write sins not tragedies (song about closing a door), here are their five eras so far
A fever you can't sweat out: weirdly sexual phase along with strange religious lyrics and every song is a bop (and outfits and makeup are on point)
Pretty. Odd.: Beatles phase with very lovely vocals provided by Ryan Ross and all the emotions your emo little heart can handle
Vices and Virtues: the extremely and shamefully underrated steampunk era where the instrumentals and outfits were once again on point
Too weird to live, too rare to die!: electronic music that you can't help but dance and sing along to
Death of a bachelor: full on rock album that might shatter your ears with the beautiful high notes and will make you cry with a random emotional song at the end
As you can see, I've given up on trying to be a fancy-schmancy reviewer
