BOOTH DOES NOT INCLUDE ADMISSION---LIMITED SEATED SHOWS--- Writers love phrases with multiple meanings; they’re so much handier than mere single-idea word strings. That’s why it’s so perfect that The Trishas’ first full-length album, High, Wide & Handsome, kicks off with a track titled “Mother of Invention.” Not only does it hint at the four members’ capacity for resourcefulness and their entry into motherhood, it also, by extension, suggests the concept of family itself. And family not only describes the sisterlike tightness of their bond, it’s literally what drew them together in the first place. (The Zappa nod is just icing.) When Jamie Wilson, Liz Foster, Kelley Mickwee and Savannah Welch first shared a stage in January 2009, their intention was simply to perform a couple of songs as part of a tribute to Savannah’s father, singer-songwriter Kevin Welch. They had no plans to pursue a joint musical future — they didn’t even have a name, and wound up calling themselves The Trishas on a whim (it popped into their heads because they were covering a Welch-authored Trisha Yearwood hit). But when magic happens, sometimes you have to give in to its power. The sound of their voices soaring in close four-part harmony so transfixed listeners that night in Steamboat, Colorado, that show offers began to come in, luring them into testing the waters as a group. By that September, The Trishas were showcasing at the Americana Music Association Conference & Festival in Nashville, where Raul Malo caught them. He invited them to sing on his Sinners & Saints album. Ray Wylie Hubbard recruited them for his lauded release, A. Enlightenment B. Endarkenment (Hint: There is no c). Warner/Chappell Music signed them to a publishing deal. They toured with the Nitty Gritty Dirt Band and Todd Snider, performed with Malo and joined Savannah’s dad on his album, A Patch of Blue Sky.
