The 2016 record by Four Thing, date added 2019-10-28.  It's on Bandcamp, four people perhaps doing some sort of exquisite corpse thing?  The four people trade off lines which may or may not relate to each other narratively, the singing has melodies, the music is pretty dissonant and seems more like a bed to inspire the four singers.  The blurb is in the same sort of arty vein.  Occasionally the singers are singing in unison.

I don't know where it came from.  Maybe one of those RYM lists.  I don't know how I'd compare it to the Five Men Singing album.  They're not comparable, you know, there are women in Four Thing for one.

Tomsix, one of those late '70s American prog bands that shaded into disco.  "Lookin' for a Little Light" is one of the best prog disco cuts I've heard.  There should be more '70s prog disco.

"Episode Six were an English rock band formed in Harrow, London in 1965. The band did not have commercial success in the UK, releasing nine singles that all failed to chart,[2] but they did find minor success in Beirut at the time.[3]" - Wikipedia.  The only song of theirs I have is an off-air BBC recording of Love's "Alone Again Or" from Garage Tape No117.  I honestly never gave a shit about Deep Purple.

(Episode Six may have done OK in Beirut... Pink Floyd did well enough to get "Point Me At The Sky" released as a 7" in Egypt, however, Columbia over there released it under the name "Pink Floid", which for some reason makes this particular release particularly collectible.)

"Writer Nat Hentoff once famously wrote that if his building was on fire and he had time to grab only one jazz recording to save, it would be a session that celebrates its 76^th birthday today; The Kansas City Six." - The Jazz Museum in Harlem.  The track I have is from a comp called "Dark Sweets A"; it's called "Pagin' the Devil".  There's a song on "Dark Sweets B" called Peter Gink by the Six Brown Brothers.  It's from 1919 though and is hard to listen to the way the acoustic recordings sometimes can be.

Out on Blue Six are a 1980 post-punk band best remembered for their Peel Sessions.  Music writer Ian McDonald remembers the name and later named a novel after the band.  He regrets the novel.  Cory Doctorow likes the novel.  The music is very good, though given that I'm fond of 1980 post-punk anyway I might be biased.

Take Six is an unknown library project, probably riffing on Brubeck's "Take Five", who put out a number of library music records on Hudson, Rouge, and De Wolfe in the late '70s and early '80s.  Their song "Bach 2001" is a monster fugal bit of analog synth-funk.  One of the curators posted it to their Youtube channel on Nov 16, 2016.  Added to my library on December 23, 2019, probably from a /r/vintageobscura upload.  As of this writing it has 1,412 Youtube views.

Well I could talk about Sixting Music, Six Finger Satellite, Stormy Six, but already know about those I'm assuming.

Maybe next time I'll get as far as the number seven.
