His interpretations of the classics were often tasteless but competent for sure. I heard him live at Radio City Music Hall (free tickets someone didn't want), and a great deal of the show was bad jokes about being in or out of the closet

but he did do his boogie woogie 8/16/32/64 to the bar thing, which was one of the most amazing LH feats of pianism I have ever seen

and the end of the "concert" was a 7 to 10 minute Liszt Rhapsody arrangement with orchestra, focusing on the 2nd Rhapsody but including quotes from several others. He brought this to a shattering climax worthy of a great pianist.
He could have been a great pianist, but chose to b a great showman instead. That said pianists often wrongly deride or dismiss his pianistic abilities, which were considerable but overshadowed by the showmanship.
When in Las Vegas visit the Liberace Museum, a fascinating and bizarre glimpse into his life and personality, and one of Chopin's (maybe) pianos and Gershwin's Chickering concert grand are there too.
BTW, about Elvis' showmanship; HE copied Liberace, who designed and bought the gold lame outfits for Elvis and coached him in stage presence and prersentation.
But enough of this...
