Eraserheads went onstage for their reunion concert on August 30, 2008, at The Fort Open Field, Taguig City. The concert, however, was cut short halfway through a planned 30-song setlist as Buendia was rushed to the Makati Medical Hospital after experiencing chest pains. He was reported to be in stable condition. Buddy Zabala had checked on Buendia in his tent right after they went to their planned 20-minute break and saw that he already was on an oxygen mask with paramedics checking his blood pressure. As he left and came back, paramedics were already taking Buendia on an ambulance. Bandmates Zabala, Marasigan and Adoro further said that they had no idea that Buendia was already having difficulty performing. In the spirit of the reunion, Marasigan, Zabala, and Adoro went to Saguijo after the concert and they continued their sets there. Kris Gorra-Dancel, Ebe Dancel, Aia De Leon, and many other OPM artists joined them as well. During the concert, Jazz Nicolas of the Itchyworms and a close friend of the band, also joined the band and played synths, keyboards, and other back-up instruments.
