Extremely anaemic hideous canned music (9)

I haven't cracked this one yet — but the brilliant team at Fifteensquared have:

A naemi C (first and last letters only or ”extremely’) and an anagram (‘canned’) of HIDEOUS. We don’t remember seeing ‘canned’ as an anagram indicator before. We suppose that if you put things in a can they may not be in the same position as they were it was before they went in!
