Owing evidently to Tom Kenny's appearance, in the finally released first volume of the three part DVD voice over documentary series, Adventures in Voice Acting, there is a clip from a Foster's recording session with Tom and Keith Ferguson. Since the first volume is chiefly about anime, it's really part of a mini-segment regarding the differences between anime dubbing and original voiceover. (A few moments later a clip from "Bloooo" with Wilt and Eduardo where Wilt asks about Eduardo's potato sack is shown.
) Evidently Tom was part of the volume due to his involvement in IGPX. (The series' other featured stars, Haley Joel Osment, Michelle Rodriguez, and Lance Henriksen were also in there.)
Volume 1 of AIVA has been available at Anime Expo this past week (got mine signed by Wendee Lee - woot!) and will supposedly hit retail in a couple weeks. The following two volumes will be on games and original animation, respectively.
