The band took the stage at 2021 Premios Juventud on Thursday.
Zabdiel De Jesús, Richard Camacho, Erick Brian Colón and Christopher Vélez performed a new song, "To'a La Noche," which translates to "All Night." Dressed in black, white and gray ensembles, the group proved they're just as coordinated as they've ever been.
Pimentel announced in May that he would be leaving the group to pursue "new opportunities."
"It is with a heavy heart that I announce that May 14, will be my last day as a member of CNCO," Pimentel wrote, in part. "It's time for me to grow and explore new artistic avenues, it's time to start building my own path and career. That's why I've decided to leave the band."
Pimentel thanked the group's legion of followers, sharing, "Without you, we wouldn't have accomplished all of the most amazing things we have over the past five years."
He also went on to thank his CNCO bandmates, sharing, "I truly wish you the best as you continue on with the CNCO legacy. We've lived through so much together that we're family now."
