Sigur Rós Glósóli played on a Tonal Plexus

YouTube via AaronAndrewHunt

"This is my rendition of Glósóli by Sigur Rós, from the 2005 album Takk. It really doesn't take 211 keys in an octave to play this, but it's nice to be able to play it in Just Intonation, with different pitches depending on the voice leading. This is a single take. I tried to capture some of the grandeur of the original, though that is really impossible, and I hope you won't think my effort is too lame ... get the real thing here - IMHO possibly the best music video ever made: http://www.youtube.com/watch?v=Zr_MJA... ... more about the Tonal Plexus at http://www.h-pi.com"

Herpesz - Kórház

YouTube via Pasquerel. Roland SH-1000. Some Hungarian synth punk sent my way via Gábor.
"This is the only recording in exist from hungarian punk band "Herpesz". This video has been shot at Balatonszemes in 1985 when being a punk was an illegal thing in Hungary. The band is surprisingly good playing a strong DAF-influenced song about the hospital-like feeling of their era.
