Christian Bautista has just released his latest single, titled “Rainbow.”
The newly released track serves as a special collaboration between Bautista and Indonesian singer-songwriter Raisa for their reimagined rendition of South Border’s OPM classic, transforming the hit song into a soulful R&B ballad that combines his smooth baritone voice with the velvety vocals of Raisa.
“‘Rainbow’ is one of those songs that’s always stayed with me,” says Bautista of the track. “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.”
The collaboration between the two musicians comes as no surprise to those paying attention to their work, following their previous collaboration sharing the stage at a 13-city ASEAN concert in Japan. “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,” Bautista recalls. “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.”
Their cover of “Rainbow” marks Christian Bautista’s first musical release under his new label, Sony Music Philippines, and his latest single since “Vertigo” which was released earlier this February 2025. Aside from the release of the new collaboration single, the “The Way You Look At Me” hitmaker also teased the release of a series of joint performances and a music video on the way.
Over the years, Bautista has developed a strong presence in Southeast Asia –– particularly in the Philippines and Indonesia. His music, performances, and sincere artistry have earned him a devoted following, making him a household name throughout the country for his hit songs and regional television appearances.
