The performance was a surprise to all in attendance, including Reyna and Martinez, lead vocalist for David Lee Garza Y Los Musicales, who were also performing that night at the festival.
“Had an amazing time last night,” Martinez posted on Facebook. “Had the honor of singing with Elida Reyna y Avante. A moment I will always remember!”
Moments before performing the 2011 hit from Reyna and Jesse Turner of Siggno, which won Song Of The Year and Vocal Duo Of The Year at the 32nd Tejano Music Awards, Reyna brought Martinez on sate and the 24-year-old vocalist said that performing the duet could now be crossed off his bucket list.
