Reverting words I added that were never in this field. The stored value was exactly 'Ã?pera de Roma' — mojibake of 'Ópera de Roma' (Ó is C3 93, whose second byte was lost). The field may well be an abbreviated name, but completing it is a separate question from repairing the encoding, and guessing at it is not a repair.

Repairing mojibake (Ã?pera de Roma). Spanish rendering of the Teatro dell'Opera di Roma chorus; the corrupted byte was a capital O with acute.

Fixing encoding issue. Correct name from Spotify album 3YSdvDBjiENsS1XtJfLSWd listing Orchestra Del Teatro Dell'Opera Di Roma.
