"Michael Kaler demonstrates that the pursuit of something esoteric, essential, and religious in nature drove the Grateful Dead's artistic path. Persuasively arguing that the Dead believed that improvisational music has the power to evoke transcendence and foster collective consciousness, Get Shown the Light makes an important contribution to the growing body of work that interrogates the relationship between music, religiosity, and American culture."–Ariella Werden-Greenfield, coeditor of "This Is Your Song Too: Phish and Contemporary Jewish Identity"
