The Miami Pop Festival was organised by Michael Lang, who later went on to organise Woodstock. The event was scheduled to be a three-day event including bands such as Frank Zappa And The Mothers Of Invention, John Lee Hooker, Arthur Brown and Chuck Berry as well as The Jimi Hendrix Experience. The first day was a success but the next two days were washed out by rainstorms, inspriring Hendrix to pen the song Rainy Day, Dream Away.
