This fresh take on the South Border classic also marks Bautista’s first release under Sony Music Entertainment.
Asia’s Romantic Balladeer, Christian Bautista, has dropped his long-awaited single, “Rainbow,” out today 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 Christian Bautista’s smooth baritone with Raisa’s velvety vocals in a lush, emotionally charged arrangement that captures the kind of longing and connection that lingers long after the last note.
“‘Rainbow’ is one of those songs that’s always stayed with me,” says 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!” shares 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.”
Christian Bautista and Raisa’s rendition of “Rainbow” delivers a heartfelt interpretation of the timeless OPM classic, heralding an exciting new era for both Southeast Asian music icons. 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 recalls, “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.”
“Christian is already so big in Indonesia—I grew up listening to him,” Raisa adds. “He’s such a great balladeer and vocalist. We finally got to spend time together on that Japan tour. What I admire most is his musicality and his beautiful personality. When the idea to collaborate came up, of course, I said yes.”
Christian 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. This deep connection with audiences in both countries makes his duet with Raisa not only meaningful but a natural and highly anticipated musical moment in the region.
“This has been a long-awaited collaboration for many of our fans across the region,” shares Bautista. “We’ve both heard from listeners in the Philippines and Indonesia who’ve been hoping for this moment, so it feels incredibly special—not just for us, but for everyone who’s supported our music. We’re truly grateful to Sony Music for helping bring it to life.”
“The Philippines is a huge market with so many great singers and amazing music,” Raisa notes. “I’ve never tapped into that market before, and I want to expand my reach. I hope the Filipino audience will welcome me.”
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. With millions of loyal listeners across Southeast Asia and collaborations with some of the region’s top talents, Raisa continues to shape the sound of contemporary Indonesian pop and remains one of its most influential and admired voices.
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 explains. “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.”
“We discovered how well our vocal styles complemented each other when we performed together,” Bautista shares. “We both give our all in every performance, but we also know when to step back and let the other shine. That balance was key in making this rendition emotionally captivating and honest.”
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 admits. “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 adds. “There’s a natural connection between our audiences.”
The multi-awarded Filipino pop icon explains, “Staying true to the spirit of the original while making it meaningful for today’s listeners was something we truly cared about,” shares Bautista. “We each brought our reflections into the song, hoping it would resonate in a deeper, more intimate way—wherever in the world it’s heard.”
As for what’s next? The fans have every reason to be excited.
“We’re currently planning joint performances and a music video,” Bautista teases. “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.”
“I certainly hope so,” says Raisa. “This song will truly come to life when performed in person. It’s just another reason for me to visit the Philippines—or for Christian to come back to Indonesia! When you collaborate with a dear friend, it’s always more fun to do things together. It makes the experience that much more soulful.”
“Rainbow” by Christian Bautista featuring Raisa is now available on all major streaming platforms worldwide via Sony Music Entertainment.
