The Crooked Jades performing in Poway Friday

Take a musical trip back in time with The Crooked Jades, who will perform a concert at 7:30 p.m. Friday in Templar’s Hall in Old Poway Park, 14134 Midland Road.

The concert is being sponsored by the San Diego Folk Heritage and is open to the public. Tickets are $18, $15 for members of the SDFH, and are available at the door or online at TicketWeb.com by searching “San Diego Folk Heritage.” Doors open at 6:45 p.m.

Focusing on pre-radio music, including the music of Appalachia, The Crooked Jades has been performing covers and the group’s own original music for 20 years and have released eight albums.

The Crooked Jades was founded by Jeff Kazor (vocals, guitar and ukulele), who has remained the group’s constant and band leader through 20 years of changing members. “We’ve had several changes over the years, because we’re doing a lot of touring and a lot of the original members couldn’t take as much time off,” said Kazor.

The current lineup features two original core members, including co-founder Lisa Berman (vocals, slide guitar, banjo and harmonium) and Erik Pearson (vocals, slide guitar, banjo and harmonium). They will be joined by The Crooked Jades’s newest member, Emily Mann (fiddle), and Ellie Athayde, who will replace injured member Walter Spencer on bass for this tour.

Kazor said that while The Crooked Jades has performed in San Diego before, this will be the group’s first time performing in Poway. The show will feature a lot of original music from their last three albums, as well as some of the early music that started their career, said Kazor. “A lot of dance tunes, a lot of ballads,” he said.

The Crooked Jades was born out of Kazor’s love for early country and folk music, which he was introduced to by his father. One album he said he particularly gravitated toward was an album by the Watson Family.

He was also looking for an alternate to his generation’s music, and found it in old-time Appalachian string music. “It was really alternative and cutting-edge to me,” he said. “It felt more like punk music than anything else to me at the time.”

In addition to performing around the world with The Crooked Jades, Kazor created the soundtrack to award-winning PBS documentary film “Seven Sisters” in 2000 and produced music selected by Sean Penn for “Into the Wild” in 2007.

Kazor also co-founded the grassroots San Francisco Bluegrass and Old-Time Festival in 1999.

The Crooked Jades are currently working on a new album, one that they had originally planned to release to coincide with the group’s 20th anniversary this year. Kazor said that they now hope to release it in early spring.
