I'd better reply as I think it was my comment that inspired this thread.
Early 90s I think, we went to see Whitesnake with Pride & Glory supporting. I mainly wanted see P&G, being a big Ozzy fan previously, as it was Zakk Wylde's band.
Once at the gig we found out P&G had pulled out, bummer but nevermind, it's still Whitesnake it so should be good.
About fifteen minutes in there was a lengthy guitar solo, hmm no need for all that fretwankery. Following that, God no please don't, too late, bass solo. Oh how it dragged on, rumbling, indiscernable noise.
Anyway it finally ended and I thought great, let's hear some songs, just as the bass drum started thumping.
In a Dorothy-esque "There's no place like home, there's no place like home", I clicked my Ruby DMs together and quietly whispered, "Please let a song start, please let a song start". Nope, into the bass drum came some tom fills, then the snare rolls, then the full kit, on and on and on. Please make it stop. It didn't, not for very long time. So we all walked and went clubbing instead.
