My copy arrived today and I put it in right away.
I will start off by saying that I've never understood the bad rap that most people (including Billy himself) give this album. Maybe it's because it was the album that first turned me on to Billy Joel, but I don't think there's a weak song on this album. Granted, its best moments probably don't rival the best songs on the three albums that followed it. However, I also feel that Turnstiles, The Stranger and 52nd Street each have one or two weak tracks that I will usually skip over. Also, as a pianist who has studied his music for years, I find that of all his albums, this album has the most songs that I enjoy playing when I sit at my piano. The only problem musically that I have with this album is that Columbia was not allowing him to use his touring band and insisted he use session players. Compare the performance of "Los Angelenos" on here to the live version on Songs in the Attic. The live version blows away the original.
Now onto the mix. LOVE IT!!! Very active use of the rear speakers and very discrete. Much like the Earth, Wind & Fire. Keeps you guessing too. In one song, the piano will be behind you. In the next, the drums. As others have mentioned, the rears are on the powerful side, guess that was standard for quad back in the day, but it's nothing that can't be easily adjusted.
I honestly can't think of any criticisms on this one and the album has been a favorite of mine for forty years. (Crap! I'm old!) So I have to give this one a 10.
