This kit is amazing on its own terms. The toms have a light and ‘airy’ sound. Lots of room for the cymbals to crash as well. Actually, if Nicko did not enter the realm of Maiden, he may have preferred that kind of a sound. That being said, IMO it would be less ideal for Maiden than something like Eric Johnson (say, Cliffs of Dover). This is because Maiden needs more substance than air.
Clearly, he prefers slow--which is, in terms of his own performance--and heavy drum sounds. Given that you think the snare in Rock in Rio ’19 is too low pitchwise, probably you did not enjoy the BoS Live Chapter very much either. I love how drums sound in tRatB. His relatively ‘snappy’ bass kick gets along so well with Steve, even though it is somewhat bloated at times. Also the more meaty snare fits so well with his desire to enjoy “bam-bam”, though, especially when mixing is poorly done, it definitely risks making the soundstage congested.
