Grover probably intended to donate the organ to the New England Conservatory of Music, but after his death circa 1897, it was auctioned to settle his estate.

Beneath the vault is an entablature whose cornice hides indirect lighting which illuminates and reflects off the ceiling.

The total enclosed volume is over 300,000 cubic feet (8,500 m3), which gives a reverberation time of 4 seconds when the hall is empty.

The walls above that are plaster with brocade panels which in addition to their decorative appearance are placed to absorb excess reverberation.

This business initially prospered, building several notable pipe organs including the one for the National Cathedral in Washington, D.C.

In June 1943, a fire destroyed the organ factory building, but the music hall was largely undamaged.

In July, the mortgage sale was completed, with Essex Savings Bank buying the property at auction for $55,000.

In May 1946, eight local residents founded a charitable organization to buy and maintain the music hall, operating it as a cultural center.

The Hall is frequently rented for weddings, private and public gatherings, corporate events and other performances.

The Hall is currently open from early spring through December, finishing the season with a fan favorite holiday concert.
