It was a long time I had listened this until today and I was really suprised how great album this is! I just remembered this much more straighforward album (must be Gypsy in the first song), but there are lots of great melodies and really many songs are going towards prog, the ending Wake Up is almost epic prog piece! Other great songs are Walking In Your Shadow & Iīll Keep On Trying, but my favourite is Come Away Melinda, which is the biggest suprise with itīs great sad melodies and mellotron! Only piece that really is kind of root piece and differs the others is Lucy Blues. But also itīs not bad.
I think this Heepīs debut is much better than ones of Zeppelin, Purple & Sabbath, I think they were really ahead of time when this came and really made the base of forthcoming Heavy Metal!
