Husband and wife team Al Petteway and Amy White have been performing their mix of English folk and Irish Celtic to responsive audiences in the Washington area for more than seven years and have the WAMMIEs awards to prove it -- they've won more than three dozen, including last year's award for best new age duo. Collectively, they've mastered the acoustic guitar, the mandolin, piano, bouzouki and several world percussion instruments including the African ashiko drum. On Saturday, the couple kick off the Unitarian Universalist Church's Annapolis Concert Series. Petteway and White will perform several selections from their CDs "Racing Hearts" and "Gratitude." 7:30 p.m. Saturday. Unitarian Universalist Church, 333 Dubois Rd., Annapolis. $20. 410-266-8044.


Havana Select brings something different to Anne Arundel County -- a mixture of African and Cuban drumming, dancing and cultural traditions through music. The 12-member, Washington-based group, founded by Afro-Cuban folk musician Steve Bloom in 1985, has performed at the Kennedy Center, the Smithsonian Institution and Washington's Dance Place. On Tuesday, three of the group's drummers, including newcomer David Font, will demonstrate an Afro-Cuban religious ceremony that combines drumming with traditional singing and dance. "The whole group specializes in what is considered African and Cuban folkloric music," Bloom said. "It's the root and origin of things like salsa, like the rumba. These are very popular song and dance forms, but we perform the range of folkloric stuff, including the sacred." Performance includes lecture. 12:30 p.m. Tuesday. Room 224, Cade Center for Fine Arts, Anne Arundel Community College, 101 College Pkwy., Arnold. Free. 410-777-7230.

The British playwright examines ideas of romanticism and existentialism through the work of a mathematical genius, 13-year-old Lady Thomasina Coverly, who predicts thermodynamics and studies fractal geometry.

Directed by Craig Allen Mummey and performed by the Colonial Players. 8 p.m. Thursdays through Saturdays, 2:30 p.m. Sundays, through Nov. 16.
