In 2010 and 2011, Pavel Zajíček performed with a chamber program called Sinusoida. 32 short texts spewed into a hypnotic background of music written by Tomáš Vtípil. The next, and last, musician was Michal Koval on bass guitar. The monotonous rhythm, only occasionally disturbed by Vtípil's sound electronic intervention, flows like water. Vtípil himself says: "I primarily came from the name Sinusoida. It is built on a certain wave, there are different gradations, mirroring. It's an open, fluid thing. The responsibility of individual people is important, because when there is so much openness, discipline is also needed." To edit the recording from 2011, I approached Vtípil, who enriched it this year with his prepared piano and Monika Načeva's voice, which gave the recording another dimension.
