Can we draw the following hypothesis from the context?

Context:

System of a Down is the debut studio album by Armenian-American metal band System of a Down, released on June 30, 1998, by American Recordings and Columbia Records. The album was later certified gold by the Recording Industry Association of America on February 2, 2000. Two years later, after the success of System of a Down's next album, "Toxicity", the album was certified platinum.
