There are at least four artists with this name.

(1) Ism was and is (?) an American punk band from Queens, New York, first releasing a 7-inch in 1980. The four-member group played hectic, fast punk. In some songs the band is using a keyboard or a piano that’s creating a remarkable sound. Most of the original recordings are rare.

(2) The name "Ism" was used by another band from New York in the 2000s. They released a few albums but now appear to be defunct (no new material for years and their website is down). While likely aware of the original band, they claimed to have filed a U.S. trademark for the name.
