This might be a band that you've never heard of, but I'd highly recommend you guys checking them out.
They completely rock.
The best way to describe their music is hard rock, with progressive elements thrown in. They're highly influenced by bands like The Beatles, Genesis, Pink Floyd, Queen, Rush, and etc.
Their 15th studio album, "Machine", is up for preorder and Glenn Workman (who's a band member - the band presses their own cds, isn't that cool?) said that he sent the cds out yesterday, so I'm really looking forward to hearing it.
They've had many lineup changes over the years, but have retained the same classic sound. Their first album was released in 1975.
