Surface modeling learning resources [Video]

Having searched through youtube for quite a while, I am having difficulties finding many in-depth, narrated, intermediate to advanced level (Nurbs) surface modeling tutorials. Simply Rhino has some nice ones, as well as the official Rhino Tutorial channel on Vimeo (especially Kyle Houchens’ videos). Do you have any other recommendations other than these?

There are some nice videos by @Mark_Landsaat on Youtube, in my opinion.

How to Rhino its an excelent channel too
