Band I note providing raw food (7)
I believe the answer is:
sashimi
'raw food' is the definition.
'sashimi' can be an answer for 'food' (sashimi is a kind of food). I'm not sure about the 'raw' bit.
'band i note' is the wordplay.
'band' becomes 'sash' (a band of material).
'note' becomes 'mi' (as in 'do re mi').
'sash'+'i'+'mi'='SASHIMI'
'providing' is the link.
Can you help me to learn more?
(Other definitions for sashimi that I've seen before include "Something of chef's" , "foreign dish" , "Japanese raw fish - I'm as his (anag)" , "food in Japan" , "possible accompaniment to 26 [SAKI]" .)
