At last night’s Grammy’s, Lady Gaga did the tribute to David Bowie. It’s a sad commentary when you can’t find a popular rock artist(s) to pay tribute to a great rock icon. Not that we don’t like Lady Gaga … but it’s more telling about the state of rock music. Which is why this week we want to talk about Coachella and the huge festivals that are creating Zombie rock bands. Trust us … this will make sense and all will be explained.
