Sinatra singing slow ballads is just annoying, as is Elvis, and a lot of those country singers. They just about killed the music business in the late ‘50s and early ‘60s. Then along came the British groups and the Beach Boys reviving the energetic combo sound like jazz was before the big bands took over.
The British Invasion saved R&R in my opinion. And reintroduce America to its own music form...The Blues. Loved it.
