Farlaff´s Rondo Chaliapin recorded just twice: the first time in June 1908 (matrix 607i) and second time 9th June, 1931. In second session two matrixes were recorded (probably in parallel) - the first one 2B 582-1 was never used. Judging by the sound quality, the current record originates from 1931 recording. The indirect proof is the presence of The Miller´s aria on the other side. The same coupling has the original record HMV DB 1530.
