Christian rock, 9 p.m.
In case you’re not an acoustic-rock aficionado or former church youth group kid, a word of introduction: Jars of Clay was one of the quintessential crossover Christian acts of the ’90s, scoring at least one big radio hit, “Flood,” with secular and Bible-believing crowds alike. As with fellow Christian-but-also-mainstream act Switchfoot, they’re still kicking — and they’ve turned up the volume. Jars of Clay’s 2006 album Good Monsters marked a departure in style for the band, adding a little crunchy distortion and a heavy dose of fist-pumping stadium rock. If you catch this concert, expect to see a lot of blissed-out believers swaying to the beat and mouthing the words in closed-eyed devotion. Still, most of the lyrics aren’t directly religious, creating the ambiguity so aptly pointed out in a classic episode of South Park: Is this song about Jesus or a girl? For example, try to parse the lyrics to the band’s 2002 track “Fly” and decide if they’re about a man pursuing a woman or God pursuing a person: “And I’ll fly with you through the night/ So you know I’m not letting go/ I’m not letting go/ Tears like rain fill up the sky/ Oh my love, I’m not letting go/ I won’t let you go.” In addition to the old hits, fans can expect to hear some new material from the band’s upcoming album Inland, due out Aug. 27. —Paul Bowers SUNDAY
