Against Me! remains GOATed

Honorable mention to Wendy Carlos the mother of electronic music. Seriously, she basically completely revolutionized music by helping develop the moog synthesizer then winning a grammy by releasing an album of Bach on it (in 1968), transitioned in 1968, publicly came out in 1979, and is still around today in her 80s. She also did the soundtrack to A Clockwork Orange, the Shining, and Tron.

Kim Petras is also worth bringing up here, especially since this thread is really punk. I'm not much of a pop girlie, but her music is pretty dang good, and she's also won a Grammy, made all the more impressive by doing it while openly trans.
