Semua Tentang Kita is on the Taman Langit album, recorded by Peter Pan in 2003. I bought this album in Indonesia 2 years ago. On my recording I play 2 guitar tracks on my Fender Stratocaster and 2 string tracks on my Roland synthesizer.
Note that the default YouTube video sound quality is mono and rather poor. For better quality and stereo download the mp3. It really makes a huge difference. In fact this is true for all my recordings, but for this one even more.
I visited a concert of Peter Pan in Jakarta recently, you can watch backstage photos and read more here.
