This Day in Music: April 26th

April 26th was a pretty iconic day in music, with highs and lows. For example, this day in 1969 Led Zeppelin performed "Whole Lotta Love" for the first time, Blondie went to number  one with "Call Me" in 1980, and it was this day in 1994 that Grace Slick of Jefferson Airplane/Jefferson Starship pointed a shotgun at police at her home.
