The debut album of Bulgarian techie Kottarashky (born Nikola Gruev) is vaguely reminiscent of the music Deep Forest did for their second album 'Boheme' for which Michel Sanchez and Eric Mouquet found their inspiration in the Balkans. 'Opa Hey!' is a musical trip from start to finish in which East and West, Gypsy music, folk and dance merge effortlessly into one great sound collage.
