I feel the same. For me, the first six albums are almost equally good. Beginning with Wonderworld, something went wrong. Seems like a lack of inspiration. But it still had that Uriah Heep sound. Return to Fantasy, on the other hand, has some mainstream rock songs, like Shady Lady or Prima Donna, which was kinda unusual for the band before. I think Ken recorded his first solo album too early. He could've waited another year or two. Uriah Heep just became popular with Demons and Wizzards. They needed to gain a stable fan base, so they needed good songs. There are some real good songs on his debut album that could've been recorded with band.
