cooked up a rock 'n' roll bash in Austin, Texas – drawing revelers at the annual South by Southwest music festival who were treated to Mexican food and a performance by her husband's band. Called The Feedback Showcase, Ray's Saturday night party at Beauty Bar was all about music, fun and, of course, food.
"We both love Austin so much and we just wanted to come visit the city again and have some fun," Ray told PEOPLE about her trip with hubby John Cusimano.
While Ray served up food, her husband's band, the Cringe, provided the music. Cusimano even gave his wife a shout-out from the stage. At one point, he told the crowd, "I wrote this next song about my wife, called 'Burn,' but it doesn’t have anything to do with her cooking," prompting laughter from the packed club. Later in Cringe's set, Cusimano was joined by surprise musical guest Billy Gibbons of ZZ Top who jumped onstage, grabbed his guitar and just started playing along, going into full-out rock mode. The crowd went wild, and Ray danced and cheered near the front of the stage.
"That was totally unexpected," Ray said. "We didn’t even know [Gibbons] was going to be here – and then when he got up on stage with John, that was great! He played with John's guitar and John told me he wasn't ever going to wash it again because Gibbons from ZZ Top played it!"
In addition to the Cringe, Danish rockers the Raveonettes performed for the
crowd as guests munched on veggie enchiladas suizas, a tomatillo salsa and
macaroni cheese dish, seven layer dip and Ray's mother's bourbon chicken
with cornbread stuffing topping.
