'a record on air after release? is group' is the definition.
I know nothing about this answer so I cannot judge whether it can be defined by this definition.

'of university playing hit' is the wordplay.
I cannot quite see how this works, but
'of' could be 'o' and 'o' is present in the answer.
'hit' could be 'ram' (ram can mean to hit something) and 'ram' is found within the answer.
This explanation may well be incorrect...

'out' acts as a link.
