For purposes of this discussion, I assume "Live" means "in the flesh" as opposed to live television. In the latter case, my field expands exponentially, as it would for others in my age group (67). TV first came to my rural area of central California in around 1949-50. I was able to see a lot of great performers on shows like "Omnibus," "The Firestone Hour," "The Ed Sullivan Show" and many others - everything from grand opera to classical orchestral to jazz to pop to folk and blues. In the early 1950's, they would often show little clips of performers between regular programs. Turner Classic Movies sometimes shows these "One Reel Wonders." They ranged from old jazz and big band groups to individual jazz performers like Jack Teagarden or Kid Ory and singers such as Marian Anderson and Ma Rainey.
