I don't know All Time Low's music, but they're a bandom-adjacent band and everything I've heard about them has impressed me (most notably, they've publicly said on several occasions that they DON'T think it's cool for their fans to use anti-gay slurs and that even if you have gay friendszz! Totally! !! that still doesn't make it okay. Given the proportion of tumblr teens who think "faggot" is something you can just throw around, that made me really like the band without knowing anything else about them.)

You probably know this? But the drummer for Yellowcard was Adam Lambert's first touring drummer.

The Damned Things is two of the guys from Fall Out Boy's new band.

And I always hear good things, musically, about This Providence.

Hope this helps! I know a lot of people who might actually have music-based responses to this--would it help you if I linked it to them on twitter? I can of course not do so if you'd rather.
