Blasts from the 70's in four speakers

Sometimes on here we don't do things by halves and this week we're going back in time to some 70's albums that recently remerged.

 MFSB stood for "Mothers, Fathers, Sisters and Brothers" and were the backing band on many of the soul label Philadelphia International Records distributed through Columbia/CBS rather like the Funk Bros were to Motown and this is a pairing of their 1975 album Philadelphia Freedom that features their recording of the  Elton John hit and 1976's Summertime* which is just summer inspired compositions in a more jazz influenced Funk style which I like.
This for me is a great replacement for my so-so 2010 edition issued by Edsel on regular cd.

 The Guess Who were formed in 1969 in Winnipeg, Manitoba, Canada and were a very popular hard rocking band in North America.
This features their very polished 50's influenced  Rockin' album of 1972 and Best of Vol: 2 album of 1973 in Quadraphonic and stereo.
Volume 1 of The Best of was issued in 2014 by now deceased Audio Fidelity in stereo and quad too and I was able to pick up a copy recently which contains earlier hits like American Woman and Laughing.

I do like some Jazz and got this recent issue of Herbie Hancock's Sextant album in stereo and quadraphonic sound from 1973 that features the ARP synthesizer.

1973's Head Hunters which is acclaimed by many was re-issued by Analogue Productions in stereo and quad too in 2016.
You'll note all of these releases are on Super Audio cd also playable on regular cd playing equipment and all apart from *  which is just in stereo also have the original Quadraphonic surround sound versions issued on record and Q8 tape on the Super Audio cd layer.
