Car Seat Headrest is an indie rock band. I think Sober to Death is their most popular song? They're one of those bands that pump up the reverb on their mumble lyrics. If you like that kind of thing they're good for it.
I had absolutely no idea what sound you meant by pumping up reverb on mumble lyrics (I could picture it sonically but couldn't think of an example I'd ever heard before) so I look up that song! And I have determined that they're definitely not for me. I liked the instrumentation but did not enjoy the singer's voice. I understand the appeal, but it just doesn't speak to my taste.
