SEATED SHOW BUT SEATING NOT GUARANTEED WITHOUT RESERVED BOOTH. -- BOOTHS DO NOT INCLUDE ADMISSION.-- That’s how Terri Hendrix ends her first book: With a promise of more — much more — to come. More books? Yes. More music? Most assuredly. More living with passion, playing with heart and embracing the light to spite the dark — i.e., all that “Spiritual Kind” of stuff that matters most? Count on it. Because the way Hendrix herself sees it, she’s just now getting started. “I want there to be more to my life than just mere existence,” she writes in one of the essays featured in her new book, “Cry Till You Laugh — The Part That Ain’t Art.” “No matter what I do, where I go, or whatever trials this year might have in store for me, I want to remember my ability to laugh … I want joy. And hope. And inspiration. And above all, a sense of purpose.” Joy, hope, inspiration (and laughter, too) are all essential ingredients to the acclaimed singer-songwriter’s art, and it’s a recipe she’s been perfecting for the better part of two decades now. For evidence, one need only listen to her most recent album, “Cry Till You Laugh.” As the title suggests, there’s tears in the mix, too, because Hendrix likes her yin with her yang, if only to keep both honest. But rest assured this is one artist you’ll never find wallowing in misery; instead, she spins sorrow into joy and wrings wisdom from the blues. As she sings on the ebullient “Slow Down,” “I’ve been swimming in quicksand/and I’m coming up for air.” Part affirmation, part battle cry, it’s a rage-against-the-dark message that echoes throughout the rest of the entire album, from the exuberant rush of “Roll On” to the rise-from-dirt/catch-the-light resolve of the introspective “Come Tomorrow.”
