Face punk band after leader’s left discussions (9)

I believe the answer is:

dialogues

I'm a little stuck... Click here to teach me more about this clue!

'discussions' is the definition.
The answer and definition can be both related to communication as well as being plural nouns.
Perhaps they are linked in a way I don't understand?

'face punk band after leader's left' is the wordplay.
'face' becomes 'dial' (face of a clock).
'punk' becomes 'ogu' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'band' becomes 'Yes' (British prog rock band).
'after leader's left' means to remove the first letter.
'yes' with its first letter taken off is 'es'.
'dial'+'ogu'+'es'='DIALOGUES'

Can you help me to learn more?

(Another definition for dialogues that I've seen is " conversations".)

I've seen this clue in The Independent.
