Marco Antonio Solis at Viejas Arena on Friday, September 1. Mexican singer-songwriter Marco Antonio Solis is well into middle age, but he's far from surrendering his status as a heartthrob -- one he's held since he was a teen. Today he delivers pop love songs as well as regional Mexican music for fans who buy tickets to see him in concert, but his 2013 album, Gracias Por Estar Aqui, puts its focus squarely on contemporary romantic ballads. He's a huge concert draw throughout Latin America and regularly tours the arena circuit in the U.S., where his 2013 album hit No. 1 on Billboard's Top Latin albums chart. Solis debuted as a judge on La Voz... Mexico, the Mexican version of the the TV talent show The Voice, in 2013.
