SO

For the music and vocal, utter a comparison, music played on SO is like forest full of peacefullness, meanwhile PG's vocal is beatiful chirp of birds. Both of them, form unit a coolness. Like most of PG's album, SO was influenced by world music but progressive rock still as substance. This influence makes SO rich of sounds.

Something unique on SO was collaboration PG with Kate Bush on Don't Give Up and Youssou N'Dour on In Your Eyes, torro-karawang
