No Turning Back is an album in a style of music with roots in blues rock and psychedelic/acid rock, that developed where?
Heavy metal music Heavy metal (or simply metal) is a genre of rock music that developed in the late 1960s and early 1970s, largely in the United Kingdom. With roots in blues rock and psychedelic/acid rock, the bands that created heavy metal developed a thick, massive sound, characterized by highly amplified distortion, extended guitar solos, emphatic beats, and overall loudness. Heavy metal lyrics and performance styles are sometimes associated with aggression and machismo.
Neo-psychedelia Neo-psychedelia (also called "acid punk") is a diverse style of music that originated in the 1970s as an outgrowth of the British post-punk scene. Its practitioners drew from the unusual sounds of 1960s psychedelic music, either updating or copying the approaches from that era. After post-punk, neo-psychedelia flourished into a more widespread and international movement of artists who applied the spirit of psychedelic rock to new sounds and techniques. Neo-psychedelia may also include forays into psychedelic pop, jangly guitar rock, heavily distorted free-form jams, or recording experiments. A wave of British alternative rock in the early 1990s spawned the subgenres dream pop and shoegazing.
