Before Tull became prog titans, they pioneered a blues-rock marriage of fierce power and jazzy psychedelia. The riffs steering “A New Day Yesterday” are deep and smoky, heavily influencing stoner metal, while the snaking “To Cry You a Song” alters minds thanks to its effects-filtered vocals. Flute solos still play a key role, but as the fusion jam “Dharma for One” shows, they tend to be tough, brittle, and stabbing.
