Igra Staklenih Perli

The band was formed in 1976 by old school friends, Zoran Lakic (keyboards) Vojkan Rakic (guitar) and Predrag Vukovic (percussion). The band was named after Hermann Hesse's book The Glass Bead Game with musical influences by Can, early Pink Floyd, Hawkwind, Tangerine Dream and Jimi Hendrix. Until the arrival of the bass guitarist and vocalist Drasko 'Dracula' Nikodijevic, the band did not appear live.

Their first live appearances were at the Amateur Theatre Tokovi festival in Vozdovac and in the Dadov Theatre. In 1977, drummer Dragan Soc was included into the lineup. Having played numerous free concerts at Belgrade's SKC and Belgrade's Block 45, the band established a cult status and was offered to record an album. In 1978, they entered the studio and recorded their debut, self-titled album which featured the tracks 'Gusterov trg' ('Lyzzard Square'), 'Solarni modus' ('Solar Modus'), 'Putovanje u plavo' ('Voyage into Blue'), 'Pecurka' ('Mushroom') and 'Majestetski kraj' ('Majestic End'). They described their music as 'the music of the stream of consciousness'. The cover was designed by Vukovic. By then, the group was appearing with Goran Cvetic, a disk jockey and a journalist, who was in charge of the light show, slide shows and film projections during the performance. Their appearance at the Belgrade's College of Dentistry was bootlegged by Cvetic on a simple tape recorder for his personal archive.

Before the release of the second album, Drasko Nikodijevic left the band and was replaced by Slobodan Trbojevic, who was an electric bass player from jazz band 'Ptica' and Dzuboks magazine journalist, as well. The second album was recorded from August 1979 until January 1980. Vrt svetlosti (The Garden Of Light) was produced by Aleksandar Pilipenko. Cover art was designed by Vukovic and designer Dejan Popov, but the first version of the cover was refused by PGP-RTB. The album featured five tracks: 'Igrac' ('Dancer'), 'Carobnjaci' ('Wizards'), 'Vrt svetlosti' ('The Garden of Light'), 'Lunarni Modus' ('Lunar Modus') and 'Sanjas' ('You Are Dreaming'). 'Vrt svetlosti' (The Garden Of Light,1980) was promoted live on TV at fashion show in hall Beko in Belgrade. In 1982 director Stanko Crnobrnja make a short movie about them called 'Na svoj nacin'. Their last public appearance was in 1985, in the Sava Center Concert Hall in Belgrade, on the occasion of the celebration concert dedicated to the anniversary of the music magazine ITD with music critics Aleksandar Zikic on guitar and Slobodan Boba Trbojevic on bass/vox. Recordings for the third album with the work title ISP III were never released, but can be heard on the band's official MySpace.
