3) Singer-songwriter Kenny Wayne Shepherd and his band visit the Carnegie Library Music Hall on their 2014 tour. Much can be said of Shepherd’s prolific library—it’s raw, southern-styled, slightly grungy, and highly bluesy. Shepherd, 37, hails from Shreveport, La.; his southern roots are apparent in his music. Impressively, he’s relatively young compared to many of his blues compatriots, though he’s been recording music since he was only 16 years old; he released his first studio album, Ledbetter Heights, in 1995. It’s no wonder: He’s got a hell of a talent for blues guitar and boasts a strong stage presence. Since that first release, he’s carved out an enviable reputation as one of America’s most accomplished blues guitarists. Besides selling millions of albums, Shepherd has received five Grammy nominations, two Billboard Music Awards, and a slew of other awards specific to the blues genre. His current tour promotes and celebrates his newest release, Goin’ Home, which hit shelves earlier this year. Joined by the Jeff Fetterman Band. 8 p.m. 510 E. 10th Ave., Munhall.
4) Pandemic will break out at Brillobox tonight. Symptoms of this DJ dance party are a wide grin and the uncontrollable urge to shake your body parts. This strain of Pandemic, derived from world folk and contemporary dance music, could be studied, but it is better understood through collecting experiential evidence. Pandemic presents Meltdown, a hot winter mix containing strains of cool tropical vibes. Doors open at 9:30 p.m. 4104 Penn Ave., Bloomfield.
5) Good Fridays at the Warhol is a weekly party at the museum, featuring art exhibits, music, and cocktails in the high temple to Andy Warhol’s numerous talents. Half-price museum admission. 5 – 10 p.m. 117 Sandusky St., North Shore.
