I always thought it was the little section in Trepanning by Cave In
but I now think it's Lift The Veil, Kiss The Tank by the Blood Brothers
In fact, Morgan Henderson is great all album
But the bit on Lift The Veil, in the break down, combined with the keyboards is so atmospheric.
When Whitney goes 'they want you...they want you' and the bass line just came to the forefront just sent shivers down my spine
