We are glad to present here an audio documentation of one of the highlights of 2006 edition of Prague's Stimul Festival. Four masters of experimental audio and video art joined their forces in two projects named AVVA and LÄUSE. AVVA is a project of Toshimaru Nakamura (non-input mixer) and Billy Roisz (feedback video). Their set is minimal, based on quiet, high frequencies, fascinating with the smoothness of its flow and subtle changes of its structure. Then LÄUSE - another project of Billy Roisz, this time collaborating with two turntable maestros: eRikm and dieb13. The 40-minutes long set is full of unexpected quotations and references, changes of mood and atmosphere, sounds like a good fun for both musicians and listeners.
