Confirmed artists for the 2009 Sierra Nevada World Music Festival  have been announced, and tickets are now on sale. The Festival takes place June 19-21 in Boonville, Mendocino County (about a four-hour drive from SF). The lineup this year looks particularly strong (though this is not a final list, and the artist list is subject to change): Nigerian Afrobeat heir Femi Kuti; African music legend King Sunny Ade; former Black Uhuru lead singer Michael Rose; roots revivalist Anthony B; Afro-soul diva Zap Mama; legendary reggae crooner Gregory Isaacs; popular Jamaican lover's rock star Taurrus Riley; classic reggae bands the Heptones, the Itals, and the Abyssinians; nu-roots artist Etana; Nyabinghi drummer Ras Michael; legendary toasters Michigan & Smiley; dub aficionados the Easy Star All-Stars, and Marty Dread. There are some changes this year–vehicle and RV camping are limited, for one–so planning ahead is always a good idea. Feeling irie yet?
