Yes, City of tiny lights is also a great solo. I like the solo on Inca roads too. This is interesting:
"Inca Roads" in its official incarnation was premiered live in fall 1973. The guitar solo heard on the first version released, the one on the 1975 LP One Size Fits All, was recorded at a show in Helsinki, Finland -- it can be heard back in its own performance on You Can't Do That on Stage Anymore, Vol. 2 and is considered to be one of Zappa's greatest recorded solos (the one on the studio version of "Watermelon in Easter Hay" comes close).
