'the quality of sound from don henley and co makes' is the definition.
I can't judge whether this defines the answer.

'magical rock' is the wordplay.
'magical' becomes 'eagle' (I can't explain this - if you can you should give a lot more credence to this answer).
'rock' becomes 'stone' (synonyms).
'eagle'+'stone'='EAGLESTONE'

'for' acts as a link.
