Digital Drum Kits

Lots of drummers use electronic kits, or use electronic triggers (that trigger
drum samples) on their acoustic sets to augment the sound.

There are several manufacturers. I have direct experience with Roland
professional grade stuff. Amazing really. The user can dial in the drum shell
material (birch, maple, steel, brass, copper...etc), shell depth, drum head
composition, and many other variables to get a specific sound (reverb, decay,
pitch...it goes on and on).

The sound quality of the tom toms and bass drum are outstanding. Snare
drum is also excellent. The cymbals are where the tell-tale digital sound is
most apparent, IMO.

It may also be the recording - drums are almost always compressed and rarely sound lifelike on what is mastered for consumers - you may have found a good recording.

Shadorne, Martyk1 is referring to a DVD wherein he saw the drummer's electronic kit.

It may have been a stock digital drum set "brain" (e.g., d-drum, roland, etc.), but it's more likely that the pads were triggering hi-rez samples stored in a computer or sampler.
