Trumbauer's recording of "Singin' the Blues" has been examined thoroughly and repeatedly. Surely, nothing more can be drawn from its well-trod groove.
Our friend Emrah has recently posted a playing of his copy, just coming through the speaker, so no restoration, and without the directness of a transfer.
I am amazed, not just by the crispness of this shiny pressing, but by the fact that I can hear Miff Mole's trombone behind Trumabuaer's solo! Maybe this is old news to most, but it sure took me by surprise.
