Technically, his albums ARE old style recordings because they aren’t just copy and paste/grid everything/autotune it/brickwalled. I don’t see anything disappointing about a dude writing/performing/recording ALL that music by himself, I don’t know of a single other musician doing the same thing at the level he’s doing at, there’s a million dudes like me doing it in bedrooms but I’m unaware of anyone else getting airplay and gigging that’s doing it.
If he had no abilities or mediocre ones, I could see some griping around the guy, but the dude’s an above average player on every instrument he plays. And while some of the stuff might sound like Foo Fighters or Alter Bridge, there’s layering and parts in the songs that are more complex than shit you’d hear on any of their albums.
If ya just listen to the shit they’ve put on the radio like “Distance” or that “End Of The World” and take it at face value, yeah, pretty vanilla stuff, but if you actually dig into the albums there’s some great shit on there, worthy of the attention.
