It's not just that I too was angry punk rocker way back in the day, but Mr. Rollins actually articulated why wanting good sound is a noble effort better than I've ever heard!
To turn it around, and point out what almost should be almost obvious, that wanting to hear your music as best as it can be for the sake of the blood, sweat and tears the majority of musicians had to put into their work is spot on! He single-handedly tears the false labels of "dorky, twee, or techno-obsessed" and shows them for what they are: utter BS, and stereotypes that do not apply to the greater majority. It should be equally obvious if anyone would really take the time to learn anything new, but hey, learning something new is not a big priority on a lot of people's lists.
Plus, hearing that an angry, fully tattooed, dude who could howl like a rabid wolf at live shows started out listening mostly to classical, and still cherishes his Chopin as much as his Coltrane, Zeppelin and the latest rockers just warms the heart a bit.
