For 22 years now, ever since he came to Nashville from L.A., country couturier Manuel Cuevas has thrown an annual birthday bash as festive, colorful and attention-grabbing as his world-famous threads. A crowd of 1,000 people or more is not uncommon, with guests coming all the way from Argentina, Australia and Germany, and as the night rolls on, the backwoods Bacchanalia at his mountaintop College Grove cabin comes to resemble a mash-up of La Dolce Vita, the Warhol Factory and the Louisiana Hayride. This year the fest is open to the public, and the proceeds go toward what the famed artisanal designer hopes will be his legacy: a non-profit House of Manuel in Nashville that will pass his one-of-a-kind methods along to the many students who clamor to study with him. “It’ll be my last leg of the race,” says the irrepressible Rhinestone Rembrandt, who barely has room now for the many interns who seek his tutelage. This year Marty Stuart & his Fabulous Superlatives headline a 20-deep roster of musical acts that includes Rosie Flores, Paul Burch, Mia Calderon, Danny Salazar, the LoCash Cowboys and Benita Hill, and Manuel says he’s laying in 37 gallons of tequila for the occasion. Surely he’s tired of these monster bashes, right? “We dance, we scream, we sing while we’re sipping on Cuervo,” Manuel says. “How could I grow tired of that?” Rumor has it there’s also a high concentration of drop-dead gorgeous babes — something the host doesn’t deny. “I let the other guys work the doors,” he says, chuckling.
