My dad has an encyclopedic knowledge of classic rock and he just started a classic rock blog called
On the Records. He's writing brief but dense artist summaries that are easier to digest than a wikipedia entry. He's also adding personal stories about his relationship with music. His post
From Records to Playlists reminded me just how far music technology has progressed in a short period of time. Blogs! They're still neat. If you like music that was mostly delivered via vinyl you should meet my dad.
