I saw Zappa twice in 1974 and 1983. Extremely tight bands. Did not enjoy Frank when he got into his extended sermons to the audience in 1983. But his music was stellar. Just shut up and play yer guitar.
Dweezil has done an outstanding job of keeping his Dad's music alive and relevant. Dweezil is an awes e musicna and guitarist to boot. I wish he AND Ahmet hadn't fought but family and business, man...it's a drag. I read they finally agreed to disagree so the lawsuits have ended and that is a good thing.
