Produced by Joseph Cottrell, Wayne Hall, Ken Fuller and Jeffrey Crecelius

It was great to think a little about what might make up Yes’ authenticity this week. Is it possible to define what makes the output of a band - or any kind of artistic endeavour 'authentic’? Rather than try and come up with a definition of authenticity (which is probably a loftier aim than we had time for this week), Mark and I discussed what the rather nebulous concept means to us, in the context of Yes music.

We each came up with examples of what we consider to be authentic aspects in the 50+ year history of the band and how they support our ideas of what ‘authentic Yes’ is.

As always, we would be fascinated to hear what you think of this concept - please leave your ideas in the comments below.

• How can you tell if a band like Yes is ‘being authentic’?
• Is authenticity more than simply ‘sounding like the same band’?
• Beyond music, are there any other aspects that might contribute to a feeling of authenticity?
