Elvis impersonators may be a dime a dozen, but “World Class Tribute Artist” Nathan Belt actually excels at his craft and even looks the part. Beyond the cheese of his fan club ($15 setup plus $10 a year for an individual ? it’s only slightly more for a “married couple”) and online store (which sells useful items like signed scarves, $2.50 each), there’s a charismatic entertainer whose headlining credits include “Eras of Elvis” (South Wales), the Elvis Presley Expo (Yuma, Ariz.), the Muckleshoot Casino’s Elvis Birthday Celebration (Seattle, Wash.), the Grapevine Opry (in Grapevine, where he’s been charming Texan ladies for 11 years and counting), and “Legends in Concert” (Myrtle Beach, S.C.), where he’s become somewhat of a fixture. After the two-hour show, stick around for an after-party with an acoustic set, party favors (probably not the kind Elvis would’ve wanted), and a Champagne toast. $10-$35, 8pm, Josephine Theatre, 339 W Josephine, (210) 734-4646, josephinetheatre.org, nathanbelt.com.
