According to a recent post by Blair on Toolband:
Fans of the band will notice some TOOL music in the soon to be released trailer for "Captain America."
Further research by Moose revealed that the track will be 46 & 2, though as far as I can see the trailer hasn’t been released yet. Does this mean the song will appear on the official soundtrack? Have Tool sold out? Movie fans will also note that Tool featured on an early Iron Man 2 trailer, though was removed from the trailer and movie before it was released generally..
