George Olsen & His Music with vocal refrain (Billy Murray) - Say Arabella, Fox Trot (Gus Kahn - Ted Fiorito) Victor 1925 (USA) Recorded 23 June 1926, Mx Number BVE 32739
NOTE I added a few hours later: According to quite a discussion which went in progress after I uploaded this first Olsen's and one of earlier Victor's electrical recordings, here are a few interesting details which I found recently in the web http://gasdisc.oakapplepress.com/matrix3.htm
\"At the beginning of the electrical recording era, about April 1925, RCA began imprinting a V.E. in a circle near or over the matrix number of acoustical recordings, below the label of all such recordings. When electrical recordings replaced acoustical performances, it was common to use the same basic matrix number, and to replace Bb or Cc with BVE or CVE. The reader should note the difference between a matrix number with a V.E. overprint stamp, and one with a BVE or CVE prefix. The former are electrically amplified or re-recorded from the original matrix, while the latter are new electric recordings.
Victor used these releases until the Western Electric recording process could be perfected, which was not until the following year. The first electric disc recording was probably made on or about February 1, 1925, when Victor allowed radio station WEAF in New York City to broadcast a recording by the violinist Renée Chemet.\"
