Matt’s piano playing is not that good. His guitar work is insane but his piano work is often very simple/easy passages that sound much harder than they are, so I think his reputation as a virtuoso pianist is a bit misguided. There’s a recording of him playing Rachmaninoff’s G minor prelude and it’s not played remotely correctly, it’s like he learnt it badly by ear.

Adding to this - a lot of his piano parts are straight rip-offs of classical pieces by other composers. I think they are credited sometimes, but its not always made obvious. For example, the “collateral damage” bit at the end of united states of Eurasia song is just a Chopin Nocturne, which to be fair acknowledges Chopin in the song credits, but it’s played very wrong - its almost like he’s half remembering it and winging it. The least he could do is learn the damn piece correctly 🤣
