Stylistic Changes is the first full-length solo album by Norwegian Progressive/Heavy metal guitarist Carl August Tidemann.
This growth was fueled in part by stylistic changes that had widespread appeal, and in part by the founding in 1990 of the The Contemporary A Cappella Society (CASA) by Deke Sharon and Rex Solomon, which enabled interaction and collaboration of a cappella groups across the United States for the first time.
From 1929 until 1931, Redlich studied musicology at Frankfurt University and completed a dissertation on stylistic changes in Monteverdi's madrigals.
