From their site:
"Ronstadt Generations represents the multi-cultural roots America was founded upon. Dating back five generations in North America, Michael J. Ronstadt, younger brother of Linda Ronstadt, continues the family tradition with his two sons, Michael G. and Petie.
These three voices -- all multi-instrumentalists and solo artists in their own right -- bring to life a repertoire that reaches back to the end of the 19th century while continually looking ahead into the 21st, with a rich innovation of original material alongside traditional Southwestern and Mexican songs.
Each comes with the highest credentials, having appeared around the world in performance and on recordings with such diverse artists as Linda Ronstadt, Los Lobos, the Dixie Hummingbirds, Muriel Anderson, Big Bad Voodoo Daddy and countless others.
Enjoy a fascinating musical journey with Ronstadt Generations."
