BOP aka Thomas Bjelkeborn and Paul Pignon feat. Martina Claussen (SE/AT)

The duo BOP was started in 1996 by Thomas Bjelkeborn and Paul Pignon through a common interest in computermusic development work at EMS, the Electronic Music Studio in  Stockholm. Both composers sought forms to move the often intricate programming-technical and studio-oriented electro-acoustic music onto a live stage to instill life into the in those days hardcore fixed media culture. The duo have toured extensively internationally and in recent years often as part of the ensemble SoundQuartet with the support of the Swedish Cultural Council. BOP is represented through releases from Fireworks edition and Lamour records. In BOP Paul Pignon plays assorted reeds, flutes and didgeridoo and Thomas Bjelkeborn plays various electroacoustic instruments, wii controllers and computers often complemented by oscilloscope and digital cameras for experimental visuals. All electronic sounds and transformations heard from Thomas Bjelkeborn in the compositions by BOP is created in realtime from the acoustic sounds of Paul Pignon’s multitude of instruments.

Paul Pignon was in the UK where he began playing jazz at age 15 and while studying Physics in Oxford he made his first forays into non-idiomatic improvisation. He abandoned his Ph.D research at Oxford in favour of music and moved to Yugoslavia where he is the cofounder of the Radio Belgrade Electronic Studio. In the 80ies he moved to Sweden with focus on composing and developing computer music software at the EMS Stockholm. He was the Producer at Fylkingen 1988-1992 where he also runs his concert series The Pignon Agenda.  He is still active as a composer of electronic and instrumental works in SQ, BONON, 2+ with Liisa Pentti, The Great Learning Orchestra and other ensembles in Sweden and abroad.

Thomas Bjelkeborn is a sound artist, electronic musician and electroacoustic composer living in Sweden. He is known in contemporary music circles since 1988, primarily established as EAM composer for international festivals, often in the context of residencies at prominent music institutions. In his work, he investigates the relationship between traditional acoustic instruments and it’s electronic extensions, where new physical-digital instruments often are combined with advanced audiovisuals. He is curating regular concerts at Fylkingen Stockholm and have curated new music festivals in Sweden since 1990. He has performed compositions and electroacoustic music on all continents and tours frequently in Europe with various live electronic ensembles.
