I am intrigued by the sound of what I assume to be a Double Bass played with a bow in "Sometimes I'm happy" by Lester Young, between minute 1 and minute 2.
If I am listening correctly, this seems like a Double Bass playing its line in octave doubling, as guitarists and pianist often do. Is that right?
If so, how the hell do you do that on a Double Bass? Is it at all possible without altering the tuning of the Double Bass?
If it's something else, any idea how that sound was produced in this particular tune?
