I've seen this trio twice now in LA and it is more stoner metal than stoner rock -- much more aggressive, driving rock than I expected from 2/3 of Che. Haven't heard the ep yet, but these are three talented guys just letting it rip with just enough desert vibe to still classify it in the stoner genre.
Definitely more agressive, kinda like last Fu Manchu album maybe? Surprised Gusto are kinda under the radar, not seen much about em on stonerrock.com. Should appeal to people on here.
