2011 collection featuring cuts from shuggie otis, sly & the family stone and aretha franklin.. the old grey whistle test has now been synonymous with quality music for 40 years. although possibly best know as a show for rock music, the show maintained an amazing variety when it came to choosing its artists, it really only had two criteria, 1, that the artists had released an album and 2 that they produced great music. this collection mostly features artists that appeared on the show but also include artists who for whatever reason didnt or couldnt appear on the show.
