I thought he sounded great. I remembered seeing this one on You Tube awhile back and all the accompanying negative comments towards Wolfgang's playing, IIRC somebody actually commented he ruined the song or something. Some harsh critics out there man, I think the kid sounds great.
In a recent interview, Eddie said he played piano first, drums second, then guitar. I have never heard him drum. I guess he put his kid on the same plan.
Not unless he's made massive strides from the last time I heard him. I think Rhythm is a good fit, and I dont mean that disparagingly as he's no slouch at all on the bass.
