There was also a release of the quadraphonic version in the UK in fully discrete four-channel form on the 'Quad-8' format, a four-channel variant of the stereo 8-track tape cartridge. The SQ quadraphonic mix was released on LP in a matrix format compatible with standard stereo record players. This was the first Pink Floyd album to be specially mixed for four-channel quadraphonic sound as well as conventional two-channel stereo. Ron Geesin, who had already influenced and collaborated with Roger Waters, made a notable contribution to the album and received a then-rare outside songwriting credit. A remastered CD was released in 1994 in the UK and the United States, and again in 2011. It was recorded at Abbey Road Studios in London, England, and was the band's first album to reach number 1 in the UK, while it reached number 55 in the US chart, eventually going gold there. It was released by Harvest and EMI Records 2 October 1970 in the UK, and by Harvest and Capitol on 10 October 1970 in the US. VINYL LP - Atom Heart Mother is the fifth studio album by English progressive rock band Pink Floyd. Getting hold of proper Quad turntables and vinyls would be quite an expensive and tiring task.ATOM HEART MOTHER 2016 version. If you have the 5.1 versions, then enjoy them. On the other end of the spectrum, Division Bell only has a 5.1 mix, and there's no way to compare it to a Quad version because it never existed. Now, remember: Atom Heart Mother has never been mixed in 5.1, so the only option is to get the Quad LP. I have no Quad equipment to confirm that, so no way to tell by myself. In specialized forums you sometimes read people tend to favor the Quad mixes done in the 70s because they have a different instrument and vocal placement that sounds more natural. If they had been thought for Quad from the beginning that would be a different story. So in either case you only get a re-interpretation of the original product. So they were kind of an afterthought (the quad Atom Heart Mother was released almost 3 years after the stereo, and actually even after Dark Side was released). Quad mixes were done after the stereo albums were finished and already in the market.
