Speaking of Michigan bands that started private and then moved to a major label (see The Free entry). From Lansing, Maxx starts off in heavy rock territory, with some almost metalish guitar. It's a good tune too, better for my tastes than The Free. Best I can tell, the Mainstream release is a promo that features the first track only. The second song is fairly lengthy for a single at five minutes, and contains more of a jazzy trippy sound with meandering lightly tuned guitar. I like it too - so having the original Signal press is the way to go here.
