With its “On With the Show” theme, the Marin County Fair has a fully packed week of attractions, and the concert lineup is jammed with great performers. Kicking off the five-day affair is classic-rock-radio mainstay Kansas, who found themselves back on the charts this year thanks to a documentary on the band, Miracles Out of Nowhere. Other highlights include Oakland big band La Misa Negra, Southern rockers the Marshall Tucker Band and Bay Area favorite Pablo Cruise. Capping off the fair on July 5 are two iconic singers, Judy Collins and Aaron Neville. The Marin County Fair runs Wednesday, July 1, to Sunday, July 5, at 10 Avenue of the Flags, San Rafael. Concert admission is $50. 415.473.6800.
