Since 2008 he is a member of electronic music collective DIISSC Orchestra. Their debut album D.O., released in the same year and including pieces by five composers including Jasenka’s Minefield, was Best Electroacoustic Work at the composers’ competition organized by the Lithuanian Composers’ Union. Antanas Jasenka started his creative career as a composer writing concert pieces for acoustic instruments. However, his electronic and electroacoustic music is now much more in demand. It is intense, dynamic, and multilayered, populated with diverse electronic sound objects, from harsh noise to glitch and soundscapes (as in his multimedia release Boarding Pass). The composer is often found involved in collective sound projects and interdisciplinary collaborations with various sound, visual artists and writers.
