Ang Ating Musika (; ) was a concert residency by Filipina singer Regine Velasquez at the Aliw Theater in Pasay. The residency began on November 9 and concluded on November 24, 2007, after completing six shows. The set list featured all OPM numbers that were curated from the catalogue of Filipino composers and songwriters. These included material from George Canseco, Ryan Cayabyab, Rey Valera, and Basil Valdez, among others. The show was produced by Aria Productions, with GMA Network as its broadcast partner. Velasquez served as the stage director, while Raul Mitra was chosen as the music director. Martin Nievera, Jona Viray, Aicelle Santos, Maricris Garcia, and Kyla performed as guests. Reviews for the shows were generally positive, receiving praise for the theme and Velasquez's live performance. Background and development Regine Velasquez's early-career music was rooted in OPM, which were dominated by "kundiman" ballads and bubblegum pop love songs. A musical style that was particularly apparent during the late 1980s when she released her self-titled debut album. In an article published by the Philippine Daily Inquirer promoting her reality show Celebrity Duets: Philippine Edition on October 14, 2007, Velasquez revealed that she would headline a concert the following month at the Aliw Theater in Pasay titled Ang Ating Musika. The show's name and concept was crafted from Velasquez's desire to perform OPM material, which she described as a "tribute to the country's best songwriters and composers". The set list featured songs selected by Velasquez and her team from the catalogue of notable Filipino musicians, including Freddie Aguilar, George Canseco, Ryan Cayabyab, Louie Ocampo, Vehnee Saturno, Rey Valera, Basil Valdez, Yoyoy Villame. The show was produced by Aria Productions, in partnership with GMA Network. Velasquez served as the stage director, while Raul Mitra was chosen as the music director. Martin Nievera, Jona Viray, Aicelle Santos, Maricris Garcia, and Kyla were selected as guest acts. Velasquez described the song selection process as a daunting task, saying, "I don't want to miss out on any song or songwriter that's why I thought of doing two concerts-in-one." During planning and rehearsals, the production team initially came up with eighty song titles, which was eventually reduced. "Narrowing it down to only 19 proved difficult, if not impossible", she said. At Velasquez's request, several living composers and songwriters were invited to attend the concerts. Ang Ating Musika was aired as a television special on December 2,
