I've seen a few, shall we say, "community performing art center" level tribute performances...Beatles, Hank Williams, Queen. In all instances, the band not only did a good job sounding like the band or artist, but they sort of played the part with mannerisms and costuming. My question is whether a tribute band could be successful covering the music as convincingly as possible, without the band dressing up, acting like, and having instruments similar to, the original artist? I think a band like a Steely Dan Tribute band could get away with this more easily than a Kiss Tribute band, for example. I've been wondering about something like "An Evening of the Music of Elvis" where perhaps the music is played faithfully as possible, the singer imitates Elvis exceptionally well, but without the jumpsuits, etc. The band could dress say, in jeans and rolled up white t-shirts and wayfarer sunglasses, and maybe in bell bottoms or something 70s looking for a 2nd set. And maybe there'd be sort of stage-set type items like a jukebox or something corny. Maybe even use those 50's looking stage microphones. Is the Elvis costuming so extremely vital to the tribute aspect for the lead singer, that it couldn't really be done any other way?
