Pink Floyd - Atom Heart Mother - Hyde Park, London, July 18, 1970 download

Disc and Music Echo quoth thus:

    Over five hours of varied and contrasting music was topped by a performance by the Pink Floyd, who treated the gathering to a preview of their forthcoming album. They gave an hour of beautifully mature music , soothing and inspiring to listen to. They kept the numbers short- apart from the finale -and carefully restrained. With the sun glinting on Nick Mason's drums and the clouds breaking up overhead, it seemed as if the sounds were dropping from the sky itself.

After a quiet and lazy bluesy introduction, they went gently into Green Is The Colour and Careful With that Axe Eugene.  Even in the latter the volume was down and the mood reflective. Set the Controls was at its most ethereal , the smooth crescendos flying away over the heads of the captivated audience. To end, a brass section and choir were brought on for the final 25 minute finale.

   The piece began with an arrangement for the brass and then switched to a lengthy choir pattern , followed by a dash of marvelous Floyd rock -jazz , in came the brass again , pursued by incantations from the choir and swirling special effects in two channel stereo. A reprise took up the original theme, based on a simple chord progression akin to the finale of The Man  and group, choir and orchestra projected it together in fine combination .
