What Caused The Change In Journey's Sound

There is often a lot of talk about Journey's sound. Most people obviously associate it with the vocal stylings of Steve Perry. That makes sense to a degree since the vocals tend to be a focal point of a band, especially when dealing with someone as distinctive as Steve Perry. But there is so much more th it than that. Journey has a distinct sound regardless of the vocals and much of that is due to Neal's guitar playing.
But I was listening to my iPod last night at work when Where Were You came on. I haven't been listening to much Journey because of all the drama lately but this song sounded great. And as I listened to it I came up with my opinion of where Journey's sound changed the most. For me, it was not the addition of Perry to vocals because you can easily here characteristics of the pre-Perry material on Infinity as well as Evolution and Departure. Drummingchanged a lot when Smitty came on board, but that is not as obvious to most people. And I was thinking about the fact that I always point to the addition of Cain as the biggest factor on Journey's success. But not even his lyrical addition made the biggest change in sound. I do think, however, that he is still the cause of the biggest change.
With the addition of Jon Cain to the band we got a change in the primary songwriter. Of course he was a part of the triumvirate know as Perry/Cain/Schon but he definately affected the songs. And since he was likely bringing in more material than the others I think the WAY songs were worked on changed. In the past I think it is likely that song ideas started on the guitar. The riff on Where Were You exemplified this. I think Neal would likely bust out a riff or song structure that the guys would then work around. With Cain coming in I think that starting point changed to the piano. Simply the instrument of choice but I think that is what led the band to sound different. That is what led the band away from sounding "rock".
