Still a big fan- powerful tunes with great musicianship. And I still air guitar to it.
I’ve heard some say that Zach makes them embarrassing, and I can see why, but it’s not cringingly political like latter day Muse. Yeah, he does have the odd dud line, but is anger is specific and crafted. Also, his delivery is great.
I’ve often heard the argument about many heavy bands (Deafheaven, Converge, Isis, most black metal), mostly from those who don’t listen to it regularly that they can appreciate the music but the vocals should be different. For me though, for those bands, as for RATM, the vocals and lyrics are absolutely pivotal to the essence of the music. Take those away, and you have impressive musicianship, but very little soul or conscience to connect you to it.
Liking RATM might be a generational thing though. Two of my old mates are record collectors who just dismiss them out of hand, like they would a hair metal band.
