I've never had the pleasure of meeting Larnell Lewis but I've been a fan of his for quite some time. His latest Drumeo video features him hearing and playing Metallica's "Enter Sandman" having never done either before. Hats off to Drumeo for showing something that is rarely seen in a video... the drummer listening and absorbing an entire track right before having to play it. It's a situation that most musicians have found themselves in whether listening down to a demo in the studio or having someone adding a song before going on stage... it can be scary if you haven't worked on those muscles.
There is no doubt about Larnell's listening ability and his technical level behind the kit is extremely high. But... notice how open and curious he is while listening down to the track... to me, this is the real lesson. I believe a lot of drummers worry too much about 'the sanctity of drumming and music' that they're opposed to things outside their comfort zone or what they perceive is 'the community acceptable way of drumming'... like a jazz drummer playing hard rock or using a high tuned piccolo snare as your main. This narrow mindset even carries over into kit configurations too but that's another conversation all together.
I'm not saying you have to be a fan of <insert whatever genre you never listen to> but you should at least know the mechanics of what makes it tick. Music is music is music... whether it is jazz, zydeco, orchestral, electronica, etc... and then EVERYTHING can become a source of inspiration. As an example, how different would Rush have been if Neil Peart had not been open to orchestral, world percussion, and electronics?
I'm guessing that a lot of people's take away will be either a comparison of Larnell and Lars' technique, berating one of the two drummers, being surprised that he didn't rip on Lar's drum part, or complimenting a 'non-hard rock drummer' for being able to quiet his 'fusion sensibilities' for the sake of the song... and all of these absolutely miss the point.
YouTube is full of 'out of their element' style videos like "Teenagers React To Old People Music" or "Grandparents Play Minecraft" but thanks to Drumeo and Larnell for making something that can help a lot of drummers... if they're paying attention.
