bass trombone
That sound. A veteran of quite a few groups you've definitely heard of, Seigel's resumé is staggering but still pales in comparison to his working credentials - you have no idea just how good this guy is. Exponentially increasing the impact of the ensemble with his supremely rich sound, he's also an accomplished composer and a wildly creative soloist - hear him stretch out above on the epic Seraph.
