What makes one musician a critically acclaimed darling and another fodder for mockery? Carl Wilson’s Let’s Talk About Love: A Journey to the End of Taste discusses aesthetics as seen through the adoration and hatred of Celine Dion’s album Let’s Talk About Love. Thirty-one million copies have been sold worldwide. Is it because Celine Dion has the voice of an angel who can tie the entire world into a heart-shaped knot? Or is it because Dion produces purposefully inoffensive ballads, such as “My Heart Will Go On,” meticulously marketed to your blood-pumping bosom? Walk the philosophical line with Carl Wilson’s humorous take on what constitutes good and bad taste and if these judgments even matter.
