Here is an article, thanks to Melissa for finding it. It mentions the head-injury that Pat gave Lacey during the ShockHound performance. If you haven’t seen it, there is a video player on the page the interview is on; just wait until the end. Along with somethings about Memento Mori and other details.

It took Texas rockers Flyleaf four long years to release the follow-up to their mega-successful self-titled debut. But with their new Memento Mori debuting at number eight on the Billboard 200, it’s pretty clear they haven’t lost any steam in the interim. That’s probably because they’ve never really slowed down — the Texas quintet have spent the bulk of their “off time” between albums on a relentless touring schedule, including dates with the likes of Korn, Stone Sour, Disturbed, and the Deftones.
    Though they’ve never made a secret of their faith, the band has successfully avoided becoming pigeonholed as a “Christian band.” Part of this certainly has to do with their choice of “secular,” tourmates; but the powerful rock sound of their hits “I’m So Sick” and “All Around Me” — not to mention frontwoman Lacey Mosley’s impressive vocal chops — have also elevated their material far above and beyond Christian radio’s generic Jesus-song fodder.
   Mosley and bassist Pat Seals recently sat down with ShockHound to recount their warzone adventures, tell us why Memento Mori feels more personal than their first record, and explain why they believe it’s important to live with an awareness of death.
    They also treated us to a raucous Shock Session, which ended in Mosley suffering a startling hit to the head in the last seconds of their final song, courtesy of Seal’s bass. But she’s doing okay — and apparently, this is not the first time it’s happened. -Interview Here.
