I don't know where to begin. I humbly thank you for your kind words in saying I am knowledgeable about Ambrosia, but I really don't consider myself knowledgeable in the sense that I know all about their music. I was really just wanting to comment on how flexible Pack's voice is. You've defined "needing to grow" and "Creative growth" perfectly. Thanks for that. I'm still not sure about musicians changing genres, but I see some have done well with it. I have leftover questions which I hope you'll be able to shed some light. As much as music consumes my soul each and every day, I admit I am no expert at putting music to its proper genre. My interpretations of rock and pop have always been off the mark, and really, that's okay because I never really had any reason to know who made what, until now. And even now I don't really have to, but I feel a deep interest to learn. Surfing on youtube I just accidentally ran into Eric Clapton's "Tears In Heaven" and you wanna know what I thought of this song when it came out? I thought this song came from a couple of brand new artists who were luny country boys pulled out of some bar in a redneck town and were strung out on dope or something. I never knew Clapton did this song. I mean absolutely no offense to Mr. Clapton but geez gawlly how in the name of the good lord did you come to record such a depressing song??? http://www.youtube.com/watch?v=VRsJlAJvOSM&feature=related It's a good thing you mentioned the Eagles. They are a good place for me to start figuring things out. I never thought about whether the Eagles were a rock band or not. They are also considered a country rock band. Country rock? What's "country rock?" The Eagles also recorded a bluesy-type song "Witchy Woman." So recording a song or two in a different genre doesn't mean a complete permanent change in genre, just a temporary one, it seems. Another example of temporarily changing genres is rock bands recording ballads. Don Henley's "Heart of the Matter" is an example. Another very beautiful example of this is Scorpions "Still Loving You" which has an outstanding guitar riff. http://www.youtube.com/watch?v=3uNyPefjS88 (whoops. in another post somewhere I said I didn't like heavy metal but I forgot about the Scorpions so I guess I like some heavy metal) Then you have the Edgar Winter Band which is enough to confuse anybody: jazz, blues and rock. http://www.youtube.com/watch?v=x1mV_5-bRPo More difficult genres to discern are classic rock, country rock, soft country rock, country folk rock, easy listening, and pop. All I can say is, I'm glad my job is not categorizing songs.
