Yellow Magic Orchestra - Solid State Survivor

I enjoyed YMO's self-titled debut, but Allmusic recommended their second album more.  These guys are often compared to Kraftwerk, but where Kraftwerk is steely and grey, YMO is popped colors, fun.  Here they ditched some of the traditional Asian tunes they had on their debut and save their cover song for "Day Tripper". 

I don't know as I'll keep looking for more YMO albums, though.  I do have a Ryuichi Sakamoto solo album that I've hardly listened to; maybe that's where I'll go next.

The United States of America - The United States of America

Despite releasing only one LP, the United States of America was among the most revolutionary bands of the late '60s -- grounded equally in psychedelia and the avant-garde, their music eschewed guitars in favor of strings, keyboards and haunting electronics, predating the ambient pop of the modern era by several decades. The group's lone self-titled LP, produced by David Rubinson, was recorded for CBS in 1968, its unique ambience due largely to their pioneering use of the ring modulator, a primitive synthesizer later popularized by the Krautrock sound.

Originally released on Columbia in 1968, The United States of America is one of the legendary pure psychedelic space records. Some of the harder-rocking tunes have a fun house recklessness that recalls aspects of early Pink Floyd and the Velvet Underground at their freakiest; the sedate, exquisitely orchestrated ballads, especially "Cloud Song" and the wonderfully titled "Love Song for the Dead Che," are among the best relics of dreamy psychedelia. Occasionally things get too excessive and self-conscious, and the attempts at comedy are a bit flat, but otherwise this is a near classic.
