"Tu Tapes Trop Fort":

"Simone":

Mikio Masuda

Japanese keyboardist Mikio Masuda with a legitimately smooth track, and quite possibly the best/worst album art I've seen in a while.

Mort Garson

Mother Earth's Plantasia (1976) by Mort Garson, moog instrumentation for growing plants. Mort's career started as a composer and pianist in the early 60's, but he became known mostly for the eccentric psychedelia that doused his Moog recordings. Preceeding Plantasia was Black Mass (1971) written under the pseudonym of Lucifer and meant to accompany the ceremony of its namesake; a series of singles, one for each aspect of the Zodiac; and a psychedelic re-telling of the Wizard of Oz, The Wozard of Iz (1968), complete with insane narration.
"Symphony for a Spider Plant":

"Music to Soothe the Savage Snake Plant":

"Ode to an African Violet":

"Swingin' Spathipyllums":

Suicide

Amon Düül II

Amon Düül II was one of the most influential krautrock conglomerations, with members constantly flowing in and out and branching into other groups and new musical territory. This particular period, around the release of Yeti (1970), turned out to be a seminal moment in the history of the group, marking the beginning of their underground success outside of Germany. The album shows a remarkable breadth of expression, from strange, trance-like moments of noise, constrained acoustic ragas and improvisations, to explosive, dirty, electric prog with slamming beats and tape effects.
"Archangel Thunderbird":

"Pale Gallery":

"Hallucination Guillotine":

Sister Irene O'Connor

In the 70's, an Australian nun recorded an album using a drum machine and and a derelict synthesizer; her name was Sister Irene O'Connor and the album was Fire of God's Love/Songs to Ignite the Spirit (1976).

Yes

Yes released the album Tormato in 1978, right after the success of Going for the One (1977), which saw the return of Rick Wakeman on the keyboards. This would be the final album with Anderson, Howe, Squire, and Wakeman playing together. The album suffered a bit from the musical climate of the day as punk music began to congeal in Britain. Progressive rock was becoming an old horse; people were tiring of endless, lofty instrumentation and over-your-head lyricism, both classic trademarks of Yes's early days, and prog rock in general. The songs on Tormato are much shorter and radio friendly, and despite landing on the top 10, the album was reviled amongst the formerly dedicated Yes audience and hardcore prog fans alike. With the less-than-stellar public reception, Jon Anderson (lead singer, lyricist, and composer) took the opportunity to bow out, with Wakeman quickly following suit. Still, the album does have plenty of classic Yes moments, namely the closing track (posted earlier) "On the Silent Wings of Freedom," which could stand right alongside the most raucous and inspired moments of Fragile (1971).
"Madrigal":

and the chart-topping "Don't Kill the Whale":

Devo

Before the hats came the glasses and yellow suits. Devo was formed sometime around 1973 at Kent State as a punk rock/art rock combo. They DIYed a few singles on their Booji Boy label, then were signed to Warner Bros. in '76. Here are some videos from a live performance in France in 1978, the year they released their first album, Q: Are We Not Men? A: We Are Devo.

Michael Bundt

in the mid 70's Michael Bundt played for several krautrock groups, but shifted gears in the late 70's to produce a few solo records with a decidedly spacey, funky flavor, starting with the album Just Landed Cosmic Kid (1977).
"The Brain of Oscar Panizza":

"Whose Eye Is the Sun?":

Orange Juice

hailing from late 70's scotland comes the Falling and Laughing EP, released feb. 1980, recorded in late '79 by the up-and-coming band Orange Juice. a lighter, more innocent vision of post-punk, more poppy and bubblier in tone.
