As is described by You Tube commenter Jim Neill on Serbian and former Yugoslav progressive/psychedelic rockers -
"Igra Staklenih Perli formed in 1976 and recorded their first full-length record in 1978. The group members were Zoran Lakić (keyboards) Vojkan Rakić (guitar) and Predrag Vuković (percussion) and Draško “Dracula” Nikodijević (bass guitar, lead vocals). Melding lysergic soundscapes with deep propulsive rhythms and punky vocals, the band creates a witches brew that is part Pink Floyd, some Can, Hawkwind and their own style of hardcore metallic drone."
.. and at 3.22 is that a piano riff playing the tune from the Stones 'She's A Rainbow' from 'Satanic Majesties Request' ?
and then by the time the kaleidoscope reaches 8.20 these psychedelic Serbians have realised it was actually 1979 and introduced a punk/new wave vocal that comes right out of David Byrnes and Talking Heads.
2 studio albums, 2 live albums and by 1985 that was it for Igra Staklenih Perli.
