Of the many stage performances staged at Pasar Seni ITB 2010 (ITB Art Market 2010), the Krakatao Band's performance was probably the most awaited.
Krakatau Band has a unique concept of music that combines Indonesian ancient Gamelan tonal system called Slendro or Salendro (which is known in Karawitan traditional music of Sunda, Java, and Bali) as the basis and the Western diatonic musical elements to form an energetic jazzy-feel fusion.
Their performance here I should say was very electrifying and managed to spell the audience (myself included) to sit (some even stand) still, cheer, and sing with them ever under the heat of the early afternoon sun. Unfortunately, I haven't been able to upload the video I took because of the slow internet connection. But you can listen to the sample of their musical compositions in their website that I linked above.
