Audiophile and 78 RPM record collector Jonathan Ward has started a new blog, Excavated Shellac, devoted to his collection of 78 RPM records.  His collection seems to cover an exhaustive range of musical styles, but his focus is on early ethnographic recordings, with an heavy load of African and Middle Eastern material.  He’s incredibly knowledgeable about his collection - he can give you the backstory on a recording like no one else I know.   There’s three starter posts up now, and he’s going to shoot for one a week.  Enjoy!
