Michael Murray has appeared on The Rock Cave so many times that Cave Nation is starting to wonder if he's paying rent. A man of gloriously eclectic taste, he's equally at home debating Pink Floyd's deep cuts, championing prog rock underdogs like Saga and Marillion, and somehow making Evanescence and Kim Wilde feel like a perfectly logical double feature. Mark keeps inviting him back, which either means Michael is great company or he's slowly staging a very friendly hostile takeover.
