I don't think this was mentioned before: Comiano Materdo and N’dona M’buti present: "Songs From Cape Tubbers", including a collaboration by Lee Ranaldo with members of Delicate Steve, on a cover of The Minutemen's "History Lesson Part II". You might remember Lee joined Delicate Steve to perform this same song in a live setting to celebrate the 10th anniversary of the release of Michael Azerrad's book, "Our Band Could Be Your Life":

Stumbled upon this somewhat accidentally when googling for information about a forthcoming(?) compilation by Dinosaurs In Vietnam which, judging by a vague reference on Bandcamp, will include a track by Lee Ranaldo as well (to add to Sonic 2013, perhaps?)
