Interesting. Besides him being able to do vibrato right on the keys, what else is special about this keyboard?
On another note, that article has the tracklisting for both CDs of the Making of SFaM from 2003. AFAIK, the reissue only is of the first disc, hence why it's called "The Sessions" and only one CD is pictured in the promo photo. Might be good for whoever did the article to change that.
