Sometimes a band live can be lazy or boring and sometimes they are on fire. I saw The Black Crows about the same time as this video (early 90s) and they were stoned and messy (and not in that good loose way) but here it sounds like someone replaced all their Fender amps with Marshalls then maxed all the knobs and told them to let rip.
