A section of roof at a Massachusetts music store that's home to a rhinestone-covered grand piano once owned by Liberace has collapsed under the weight of snow.

Rockland Fire Chief Scott Duffey says a roughly 100-foot-by-100-foot section of the pitched roof fell into the showroom Tuesday morning at the Piano Mill. No one was in the building at the time.

Duffey and store owner Rob Norris say it is unclear if the Liberace piano was damaged. No one is being allowed inside until a structural engineer assesses damage.

The collapse was reported at about 6:30 a.m., though Duffey says neighbors reported hearing a crash at about 1:30 a.m.

Rockland received 29 inches of snow Monday.

Norris says the Liberace piano has 88,888 rhinestones and has been appraised for $500,000.
