Wow - haven't thought of Clatter in a while. Yes, They were great, and Amy was quite the forum contributor.
On a slightly (?) less radio-friendly tangent, Julie Slick's band Echotest covers some of that ground, too (albeit with 2 basses, and varying supplemental band members as time & travel allow).
If only 21 Pilots were this good. (I just don't like them much, from a songwriting standpoint, and also from a drumming POV).
