"The group Suarasama plays contemporary compositions that draw from several traditional styles of Indonesian music and traditional music from around the world. "Fajar Di Atas Awan" (Dawn over clouds), like many of Irwansyah Harahap’s songs, is concerned with religion, here the peace that comes when faith reasserts itself after a period of doubt or distance from God. The composer, a Muslim, notes that "spiritually, textually, and musically" the song is influenced by Nusrat Fateh Ali Khan and qawwali. The melody is basically modal, and the genre requires the use of a sruti-box. To introduce elements of a contrasting system, tonal harmony, Irwansyah Harahap has added a guitar."

Suarasama was founded by Irwansyah Harahap and Rithaony Hutajulu, a couple husband-wife, who are both musician ethnomusikologists. As a composer Irwansyah Harahap was trained in several lute traditions of the world. All of Suarasama music compositions are based on musical exploration toward world music traditions either conceptually or instrumentally. All members of Suarasama band are etnomusicologists, stay in Medan city of North Sumatra province, Indonesia.
