Skastra is a ska-leaning band formed at the end of October 2015 at the FIB campus of the University of Indonesia, Depok. After changing personnel in and out of a number of times, currently there are eight members of Skastra, namely Alduri Asfirna (vocals), Ibrahim Rahman (drums), Rasmana Raga (bass), Adi Ahdiat (guitar), Fazrin Mustakin (guitar), Hanung T Wibawa (keyboard), Faris Sutowijoyo (trombone), and Taufiq Alkatiri (trumpet). SKASTRA doesn't want to limit its work in one genre, so that the music SKASTRA brought touches jazz, rocksteady, surf, keroncong and pop. In 2016, SKASTRA undertook the challenge of making a film soundtrack and writing a song entitled "Makan Hati" for the widescreen "Security Ugal-Ugalan" (2017). This single has also been played simultaneously on radio stations throughout Indonesia.
