Russian "Radio Culture" noticed an issue of M. CHekalin's Album Monoopera "What is pO...' pO" on the verses of Russian Peots A. Vvedenskiy, D. Kharms, and I. Bekhterev.
Other compositions by Mikhail Chekalin released on CD since the Millenium are certainly worth your notice. Data and reviews of some of them are available.
