Frank Sinatra and Dean Martin in their Reprise label years (from 1962), the wonderful Johnny Hartman ... is like befall.
The "Dawn of Pop" invasion brought the entertainer and crooner genre in dire straits and almost made to disappear.
What had not sing everything and accommodate for bad LPs from the second half of the 60s to the 70s, the poor singer.
A stylistic decay beyond compare. Poorer songs, worse banal pop arrangements with pop drum beat, worse multitrack recording technology, shorter titles with fades, more boring modern cover.
The 50s were the golden years !!!
