In Pictures: Flyleaf in San Francisco

Flyleaf first took off after the band's self-titled debut served up songs like "I'm So Sick," "Fully Alive" and "All Around Me." The set spent 133 weeks on the Billboard 200, and reached Top 5 of Billboard's Top Hard Rock Albums chart.

Currently touring, not only in support of their 2009 follow-up album "Memento Mori" -- Latin for "be mindful of death" -- but also as part of the "Unite & Fight" campaign against human slavery. In a recent interview with ARTISTdirect.com, frontwoman Lacey Mosley invited participation. "You fight hate with love. You fight violence with peace. You fight thieves who steal children to sell them into slavery with generosity," she said, adding that the cause can be supported by texting the word "Unite" to 20222," which adds $10 to your phone bill.

The tour stops tomorrow (10/22) at the House of Blues in San Diego and Saturday at the Orpheum Theater in Flagstaff, AZ. Next week (10/26) they wrap things up in their home state at the AT&T Center in San Antonio, TX. SoundSpike photographer Raymond Ahner attended their show at The Regency in San Francisco on Monday (10/18), and here are some of his best shots.
