Morton Subotnick, the composer (not that other Morton Subotnick you were probably thinking of), born today in 1933. He is most famous for two reasons:
1) the first electronic music piece commissioned specifically to be recorded and sold, and 2) being mentioned here on my web site. The electronic music piece is the uber-cool Silver Apples of the Moon (title is a line from a W.B. Yeats poem) recorded way back in 1967. (They had electricity back then?) If you can remember any of the many psychedelic happenings from that wild and crazy year, then you were a real square.
The first radio concert from an airplane happened today in 1922. As Jack Benny said after being introduced on his first radio broadcast, "There will be a slight pause while everyone says 'Who cares?'"
