Old acquaintance and my blogspiration Ian Zamboni is over at
sonofzamboni.blogspot.com. He covers just about everything but his real passion seems to be obscure psych/surf/garage/nuggets rock from the 60's and early 70's. It got shut down a few months ago in what seemed like an organized sweep of sharing blogs (Bigfatsatanist and a few other venerable blogs also got pinched), but he bounced back. Check the archives. On his old blogspot site there was a blogroll sidebar with dozens upon dozens of obscure and exciting blogs, but sadly it seems lost to time. Heavy emphasis on original vinyl rips (that excellent
Blood Visions rip from a few months back was his). On front page you've got The Rip Chords, Coil and Kris Kristofferson. Excellent, excellent blog.
