There is a relatively recent CD devoted to Foster's music presented in a bluegrass-inflected style: 'Swanee: The Music of Stephen Foster'. The musicians involved include Tim O'Brien, Laurie Lewis, Jay Ungar among many others whom I had not heard of - Marty Atkinson, Sarah Elizabeth Campbell et alia. It is a fine tribute to Foster and includes an excellent booklet in which the songs are discussed. There is some info and track listing HERE.

My copy is on a different label with a different cat # than the one in the above link: a Californian label - Highland Records NCD-206. Possibly, it is a subsidiary of Gourd Music.
