DUBAI: French Algerian singer and songwriter Lolo Zouai this week dropped a new music video for her single “Holding On” and announced that her upcoming album, “Reverie,” will be released on April 24.

The track, which blends R&B and dance-pop elements, explores themes of grief and memory. Its accompanying music video is dedicated to Zouai’s close friend Hanna Rosa Hotchkiss who died in 2021.

“This record was made through three years of grief, growth, and reflection. I had to lose myself to find myself again. I couldn’t have done it without my angel, Hanna.”

“Thank you to my collaborators, my friends, and my Lo-riders who held me down through it all,” she added. “I hope it heals you the way it healed me.”

Zouai teased the album earlier this year writing: “2026. ALBUM SUBMITTED. LET’S… GOOO,” on Instagram, sharing a carousel of images of herself.
