By this time Roxy Music was The Bryan Ferry Show and was the worse for it. Unlike a few, I don't think they crashed and burned after Eno left/was fired but he did produce by far the more interesting music for the rest of the 70s. But Ferry was smart and ambitious and thus, their post-Eno catalogue is strewn with great singles, like Love Is The Drug (which was a massive influence on countless post-punk bands) and Dance Away. Avalon is a bit too smooth and stylised for me but I suspect that's exactly what Ferry was reaching for.
