Yes, Sadfans, we're giving over our 75th episode to the unsung heroes of every band that ever set foot in a recording studio or onto a stage - those apparently indefatigable timekeepers without whom there would be little or no momentum.

Stuck behind the kit at the back of the stage, these are the artisans of the hard rock and heavy metal engine room.

Whether it's a sense of rhythm combined with a diver's boot (h/t to Gillan's Mick Underwood), the professorial science of Neil Peart, or the tour de force blunt trauma approach of Bonzo, these are the men and women who provide the metronome when you're standing with your feet apart and headbanging your way to an early aneurysm.

Naturally, the list of noteworthy sticksmen is ineffably long, so consider this part one of a theme the Sadmen will undoubtedly return to in episodes to come.

But for this episode the lads have picked three drummers who have, to some extent, shaped the technical art of hitting the skins with a lump of wood.

First up, Phil Collins in his second outing with Genesis for 1972's Foxtrot. Having already helped to shape the Charterhouse proggers' sound on his debut release, Nursery Cryme the year before, Collins, Banks, Gabriel and Rutherford return a year later with a release that would achieve immortality in the genre.

The boys' next stop was six years later, as Y&T - then known still as Yesterday and Today - drop their sophomore 1978 release Struck Down. Though three years away from the standard-bearing Earthshaker, this is the album that perhaps best showcases the undeniable talent of their man on the kit, Leonard Haze.

And the lads round off proceedings with Jeff Pocaro and TOTO's commercial juggernaut IV, which boasts the ghost notes on album opener Rosanna that to this day separate the men from the boys when it comes to high drumming art.

Enjoy!
