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. Solis first came to fame in the early '70s as the leader of Los Bukis (""The Youngsters""), and remained with the influential Tejano/norteno group until 1995. By then, Solis was already nurturing a solo career that would eventually grow to surpass his fame in Los Bukis. He's since notched at least 24 Top 10 singles on Billboard's Hot Latin Tracks chart, including 10 No. 1 hits.
