According to producer Ron Gibson, the Crater Cabaret will begin at noon, as first arrivals start filling the crater. The cabaret lineup: blues by Boogie, the mellow folk-rock of Johnny Helm, the reggae of Natural Vibrations and the rockin' fun of Downtown Charlie and the Humbones.

"Music will be everywhere in the crater this Saturday," said Gibson in a statement. Performers will be on the cabaret stage throughout the event and particularly before the main lineup begins and during set changes. Folks may get up to dance and the music will continue until the last patrons exit at night.

The mainstage events begin at 2 p.m., with a blessing and performance by cast members from the Polynesian Cultural Center.
