Profile of the performer @c: Working together since 2000, @c started as a trio and later shrank to a duo that ocasionally re-expands to an audiovisual trio when performing with the Austrian artist [url=http://lia.sil.at]Lia[/url]. The musical work of @c is developed in the cross-section of three complimentary approaches to sound art and electronic music: algorithmic composition, concrete sounds and improvisation. If on one hand their compositions are usually built around strong structural foundations, it's also common that multiple bits are freed from these structures when integrated into the sound work, contributing to the settling of elaborate strategies of deconstruction. Improvisation, either in dialogue or discussion, is central to @c's performances, as is the will to create open compositions and to nurture ongoing processes that digitally amplify sound realities. The creation of cross-links between referrals and memories plays with the balance between reconnaissance and abstraction. Pedro Tudela is a plastic artist and a musician and teaches at the Painting Department of the Faculty of Fine Arts, University of Porto (FBAUP). Miguel Carvalhais is a designer and musician and teaches at the Design Department of FBAUP. Since 2000, they cooperatively run the media label [l13036].
