Olli Virtaperko made his breakthrough as a composer with large-scale orchestral works, but his profile is highly diverse. He has written for big band, accordion, kantele, Baroque orchestra and the brand new knifonium instrument, among others. “I haven’t changed my mind over the general lameness, meaninglessness and boringness of crossover, but if you really know what you are doing, crossover may, on really rare occasions, work,” he says and notes that he is “a Renaissance, Baroque and Modernism man”. His interests include the curious Ensemble Ambrosius, which performs contemporary music on Baroque instruments, including a recently released album of Frank Zappa. Most Finnish people remember him as a vocalist with the highly popular group Ultra Bra (1995–2001).
