Gerap Gurita, a Celtic Punk band from Yogyakarta, collaborated with Ari Hamzah, the ex-drummer Endank Soekamti for their new single, Perayaan. The song is about finding encouragement in unpredictable situations and facing the expectations of life, with lyrics depicting the role of a father who has to step up and take responsibility. The combination of the thin whistle, mandolin, and accordion adds rich music bringing every listener to feel the atmosphere of Jogjakarta.
