Üstmamò is an Italian music group, active from 1991 to 2003. They then reformed in 2014.
The group originates in the area of the Reggio Emilia Apennines between Villa Minozzo and Castelnovo ne’ Monti, and in the local dialect, “üstmamò” means “proprio adesso”. They made their debut in 1991 with a self-titled album, sung in Italian, English, French, and Reggio Emilian dialect and interspersed with traditional refrains from the maggerini of the Apennines.
