With many people excited for the new collaboration album between Elvis Costello and The Roots, there were others who seemed to be a bit confused, as if mixing up musical influences in 2013 is something weird and bizarre. Let’s not forget that a few years ago, mash-ups were the it thing to do and hear, so if someone wanted to mix up Slayer with Conway Twitty, this was okay. Yet you do something that mixes things up in “real life” and “oh no, this is beyond anything that could happen, because it offends me”. Maybe that’s why the title is called "Wise Up Ghost" (Blue Note) because they’re telling you to wise up, and as for the ghost? Look in the mirror. Boo, you’re Casper.
