Idk I always thought what Thomas was doing was *perfectly* stated to support whatever the other musicians were playing. He's just playing the same kind of music as them. It's not showing off, it's not being flashy, it's just doing what feels *right* at the moment, being impulsive, living in the moment.
He does, in fact, occasionally slow burn, but he'll always add embellishments, and I like that. Personally, I never thought he over played or over accented, that's exactly the amount of playing and accenting that should come out of a band with 8 fucking members going ape shit crazy like The Volta did.
