Thanks for sharing this fantastic clip! One drummer was playing what looks like a standard 4 or 5 piece kit, but what was the other drummer playing? Some sort of concert tom rig? Those guys played off and with each other really well!
He was playing something what was (and is) called "Amati bongas", altough they're not bongas in strict sense of the word. Basically, they are 6.5" deep concert toms, manufactured mainly in 6",8" and 10" diameters, but they were most likely aviable in all usual tom sizes. I have a 14", but I haven't been able to get it to sound good, yet, because I don't have a proper stand for it. I use it as a bodhrán. Smaller sizes make nice ethnic/timbale-like sounds.
