A portion of Rosenblatt's original work, the cantata 'BLAGOVESTIE', has been arranged for piano four hands. The original composition is scored for vocals and orchestra. It is included as a 'Hidden track' after the 11th track on the CD 'THE MASTERS' CROSSOVER', which was produced, arranged, and conducted by Rosenblatt.

When the author visited Russia (December 2004), it was suddenly decided to prepare one more piece for the inaugural Japan tour in March 2005, and this four-hand arrangement was completed a few days later. The premiere took place on December 21, 2004. During a performance in Russia, the duo of Rosenblatt and Sinkin performed it as an encore. And upon their visit to Japan, the same duo delivered a beautiful and well-coordinated performance. The score is quite simple, yet it is a deeply expressive short piece. The performance duration is approximately four and a half minutes. The expansive melody should be played with phrases as broad as possible.
