Always liked David Izenzon's arco playing.
Mingus' arco playing on the Monterey album got to me back when - perhaps not perfect, but emotionally there & that was important to me. I was always impressed with Mingus' arco playing, given that he had so much else going on - composing, leading bands, making his bands swing. To me, it was amazing that he had the time and energy to put into it.
