Two Recordings of Verdi Requiem

[haybied]

I have two different recordings of Verdi's Requiem. I'd like to know who the tubist was on both recordings.
Atlanta Symphony Orchestra & Chorus with Robert Shaw conducting with the soloist being: Susan Dunn, Diane Curry, Jerry Hadley and Paul Plishka.
Kirov Orchestra & Chorus with Valery Gergiev conducting with the soloist being: Fleming, Borodina, Bocelli and D'Arcangelo.
