Personally, I think the song Hotel California is very emotional, and it is also a bit like "country folk rock" and "bluegrass music". The music that belonged to the western United States at that time was different from the music on the southern and eastern coasts.

Anyway, California Hotel is not the kind of rock music developed from blues music, such as the American band contemporary with Eagle: the famous southern band Leonard Skinnard. There are Pink Floyd (the Eagles were just founded when Pink Floyd became famous), Cream and so on.
