Second album of Hiro Yanagida is almost equally good as the debut one. "7sai no Rojin Tengoku" (which means "Elderly Person Heaven Of Seven Years". This album is also known under simple title: "Hiro Yanagida") doesn't bring any significant development compared to "Milk Time", but I liked previous record so much that any change in artistic direction wasn't necessary for me. We can find here lots of psychedelic organ and fuzzed electric guitar solos, jazzy drums, some spaced-out experiments (but almost never unlistenable noodling or quirky tape effects like in some other Japanese albums from early days prog...). Poor enjoyment of playing for musicians and listening for prog/psych fans. The only major difference compared to "Milk Time" is lack of violin, however Yanagida and Mizutani (along with with flute, cello & sax players) filled the disk space with enough instrumental virtuosity to keep everybody happy.
After this album Hiro recorded another 2 solo albums: simple called "Hiro"(1972) and "Hirocosmos"(1973). While I've never listened to the first one (seems to be very obscure), "Hirocosmos" is a completely different album than its predecessors. Psychedelic rock is almost completely gone in his last effort and jazz tendencies are the most evident. Hiro also mainly uses synthesizer, mellotron and electric piano instead of his famous Hammond organ (BTW Hiro recorded also album "Folk & Rock Best Collection - The World of Hiro Yanagida" in 1972, but it's non-interesting for prog lovers collection of western pop/folk/rock artists' covers).
