Creating a double album is very touch-and-go. It can be hailed as a hallmark of music (“The White Album”—The Beatles, “At Fillmore East”—The Allman Brothers Band, “Songs in the Key of Life”—Stevie Wonder), or more likely, it will fall short of expectations (too many to list). Critics often accuse them of being created solely to indulge the producer’s whims and thus state that they could often be whittled down into one strong album, rather than filling two mediocre ones. Regrettably, “Night Castle,” Trans-Siberian Orchestra’s (TSO) most recent album falls into the latter.
