Although very different in sound and style to their early records of the mid '60s, this, the Pretty Things 7th lp released in 1974, is probably their best album. Whilst it was not as ground-breaking as SF Sorrow, or as lauded as Parachute, and features a more, for the time, mainstream sound, there is not a bad track on it, and Dream/Joey, Belfast Cowboys, and Singapore Silk Torpedo are absolute stand out performances.It features their usual top notch harmony singing, brilliant ensemble playing, excellent piano and guitar work, and a stunning sound and production.
If you have never heard the 'Pretties' or this album before, try to imagine a cross between classic early '70s Who and early/mid '70s Supertramp and you sort of come close(ish)!
At this time they did have a sound very much their own though, which to my mind hasn't dated one jot, so this is definitely the best place to start investigating their post psychedelic mid period work.
If you are a fan of early to mid '60s Brit R 'n' B, you should also get some of their early stuff,(the excellent double CD compilation, 'The R'n'B Years', for instance), and fans of psychedelia will love 'SF Sorrow'. Unlike 'Silk Torpedo,' it sounds rather dated to these ears now, though.
