While I liked
Naked City, it would definitely be a mistake to judge him as a composer based on just that one album. I'd recommend another album, but my memory is gettin' bad in my advanced years
, so I can't think of an appropriate one off the top of my head. I want to say
Locus Zolus, but I can't even remember what's on that album.
As for
Hot Rats... as you may note from my sig, dissing Zappa is akin to an act of war.
Although I have to say I don't know anyone who would dismiss the talents of Malmsteen and Vai in comparison to this. Heck, Vai got his start with Zappa (an influence that is strongly evident in his early solo work). Also, this is Zappa working in a different genre.
Hot Rats was released in the same year as
Bitches Brew, and they are the first jazz-rock (or fusion) albums. While Davis' album falls on the side of "jazz with a touch of rock,"
Rats is a little more rock than jazz. That said (and let me state for the record that I LURVE
Bitches Brew), I find
Hot Rats to be a more successful fusion-- the songs on the album are all definitely BOTH rock and jazz. Brew in comparison has a taste of rock thrown into it, but noone will mistake it for a rock album. It's still jazz. Killer fucking jazz, but jazz nonetheless.
Something to keep in mind is that no one album is representative of Zappa's style. He did jazz, rock, classical... you name it, he did it, and he did it well. His influence can be heard in all styles and genres of music.
I really don't want to go into this because I'll spend all day at the computer listing off points and examples, and when it all comes down to it, people like what they like. All I know is it's 22 degrees Celcius (72 for you silly non-metric Americans) outside right now and I'm getting the hell out there! You gotta enjoy the nice weather in Ottawa when you can, 'cause it won't last...
