Very interesting to see how "limited" his role was on the band as a whole, when it came to actual vocal duties.

Take Blues for the Red Sun, for example. Dude is basically a guest vocalist in that record, he's not on it for almost half of it. 5 instrumentals in the album, including the stretch of Molten Universe, an instrumental, into 50 Million Trip, where it takes a while for him to come in, and the longer one of Apothecaries Wright, Caterpillar March, both instrumentals, into Freedom Run, where he also comes in pretty late and is mostly absent on the song. And he's not on Mondo Generator either, that's Nick singing (well, swallowing the mic).

He's definitely more present on Welcome to Sky Valley, but take Space Cadet, where it takes him about 2 minutes to come in, and he doesn't sing that much, and Supa Scoopa and Whitewater, where he comes early, but his work is done with 5 minutes or so missing on both songs, and he doesn't return.

And The Circus Leaves Town sees him more present, sans his limited roles on Phototropic and El Rodeo, but his vocals are buried to hell on some songs here.

So, it's interesting. I'm not complaining, by the way, I do love how Kyuss didnt care about rules, and if they thought an instrumental would cover space instead of vocals, they would go for it. I just really find interesting how a non instrumental band would take this approach.
