"Singin' the Blues" is probably the best-known recording of Bix Beiderbecke (and Tram and Eddie and Chauncey). By 1927, when Bix recorded "Singin' the Blues," it was an old song. It had been recorded by the ODJB and there were piano rolls by J. Russell Robinson, one of the composers, Adrian Rollini, who hired Bix in 1927 for his short-lived New Yorkers band, and, last but not least, by none other than George Gershwin.
"2. Singin’ The Blues (Till My Daddy Comes Home) (4:32)
(Con Conrad and J. Russel Robinson / Lyrics: Sam Lewis and Joe Young)
Fox-Trot, played by George Gershwin, December 920 (I think a typo; 1920), Mel-O-Dee 4133
A hit of 1920, the tune was written by Con Conrad (a.k.a. Conrad Dober of the Lower East Side) and James Russel Robinson, who worked with musician/composers Noble Sissle and W.C. Handy.
The piano roll precedes "Rhapsody in Blue" by a little over three years.
The two-and-a-half octave solo clarinet glissando opening Gershwin's Rhapsody in Blue is one of the great icons of 20th century music and one of the best known bars in music.
According to Wikipedia, "The opening clarinet glissando came into being during rehearsal when; "... as a joke on Gershwin, [Ross] Gorman (Whiteman's virtuoso clarinettist) played the opening measure with a noticeable glissando, adding what he considered a humorous touch to the passage. Reacting favourably to Gorman's whimsy, Gershwin asked him to perform the opening measure that way at the concert and to add as much of a 'wail' as possible."
I thought Gershwin wrote the intro to Rhapsody in Blue in 1924 when he was getting ready for the Aeolian Hall legendary concert of Feb 12, 1924.
But listen to the first few seconds of the Singin' the Blues Gershwin piano roll. It sounds to me like Gershwin conceived of the first few notes of the intro to Rhapsody in Blue in 1920! Is this old hat or new?
Finally, listen to the last few seconds at 4:25. What do you hear?
