Asia’s Romantic Balladeer, Christian Bautista, has dropped his long-awaited single, “Rainbow,” out now via his new record label, Sony Music Entertainment.
The heartfelt duet, featuring Indonesian singer-songwriter Raisa, reimagines the South Border classic as a soulful pop-R&B ballad blending Bautista’s smooth baritone with Raisa’s velvety vocals in a lush, emotionally charged arrangement.
“Rainbow is one of those songs that’s always stayed with me,” said Bautista. “It resonates deeply, not just in the Philippines, but also in Indonesia. Working on it with Raisa gave it new energy and meaning, and it felt right to share it in this way now.”

“Simply because I love this song — I grew up with this song — and I didn’t even know at first that it was a Filipino artist who sang it!” shared Raisa. “When I found out, I was surprised. It has such a special meaning — not just about love but about life. It’s a reassurance of rainbow after the rain. It’s something people can relate to and carry with them every day.”
The collaboration was made possible thanks to a 13-city Asean concert in Japan, where Bautista and Raisa shared the stage as fellow performers.
Bautista recalled, “We got along very well as friends and as performers during that time. It became a natural idea for us to want to collaborate. We talked about the songs we both loved, and ‘Rainbow’ stood out for both of us. That’s when everything started to fall into place. It wasn’t just the melody, it’s message of hope, comfort, and being there for someone through life’s storms really resonated with both of us.”
Bautista has long held a strong presence in Southeast Asia, particularly in the Philippines and Indonesia, where his music, performances, and sincere artistry have earned him a devoted following. Known for his romantic ballads and warm stage presence, he became a household name through his hit songs and regional television appearances.
Raisa is a multi-awarded Indonesian singer-songwriter, celebrated for her soulful voice, heartfelt ballads, and elegant artistry that have made her a standout in the region’s music scene. Known for her ability to blend emotional depth with modern pop sensibilities, she has released numerous chart-topping singles and critically acclaimed albums.
Their musical chemistry is evident in the track, with each of their distinct yet complementary vocals shining both individually and in harmony.
“With a timeless song like this, you really shouldn’t do too much,” Raisa explained. “We kept the arrangement close to the original but adjusted it to fit a male-female duet — some key changes, harmonies, and little details. Every step of the way, we made sure we honored the song. It’s such a huge song from the Philippines — we just wanted to do it justice.”
Paying homage to the original arrangement while infusing it with a contemporary, cross-cultural resonance was no small feat. With a collaborative team of both Filipino and Indonesian producers and arrangers, each attuned to the musical sensibilities of their cultures, the duet was crafted to resonate widely without losing its emotional core.
“The biggest challenge was time,” Raisa admitted. “We recorded together but couldn’t finish at the same time due to our tight schedules, so we had to complete parts separately. That’s hard for a duet — you have to match details like vibrato, phrasing… But in the end, we blended well, and I really think we gave the song something fresh while still paying homage to the original.”
“And honestly, I think Filipino and Indonesian listeners have a lot in common — we both love ballads, romantic themes, 90s R&B, and a touch of nostalgia,” Raisa finally noted.
As for what’s next? The fans have every reason to be excited.
“We’re currently planning joint performances and a music video,” Bautista teased. “This isn’t the end: it’s a continuation of a musical bridge between the Philippines and Indonesia. We hope to open more doors for future collaborations.”
“Rainbow” by Christian Bautista featuring Raisa is now available on all major streaming platforms worldwide via Sony Music Entertainment.
