Question: No Turning Back is an album in a style of music with roots in blues rock and psychedelic/acid rock, that developed where?
Context: 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. Heavy metal drumming is a style of rock music drumkit playing that developed in the late 1960s and early 1970s, largely in the United Kingdom and the United States.  With roots in blues rock and psychedelic/acid rock drum playing, heavy metal drummers play with emphatic beats, and overall loudness using an aggressive performing style.  Heavy metal (or "metal") drumming is traditionally characterized by emphatic rhythms and dense bass guitar-and-drum sound.  The essence of metal drumming is creating a loud, constant beat for the band using the "trifecta of speed, power, and precision". Acid rock is a loosely defined type of rock music that evolved out of the mid-1960s garage punk movement and helped launch the psychedelic subculture.  The style is generally defined by heavy, distorted guitars, lyrics with drug references, and long improvised jams.  Distinguishing acid rock from other genres can be tenuous, as much of the style overlaps with 1960s punk, proto-metal, and heavy, blues-based hard rock. "Psychotic Reaction" is a song by the American garage rock band Count Five, released in June 1966 on their debut studio album of the same name.  It peaked at No. 5 on the "Billboard" Hot 100, and was among the first successful acid (or psychedelic) rock songs, containing the characteristics that would come to define acid rock: the use of feedback and distortion replacing early rock music's more melodic electric guitars. No Turning Back is the second album by heavy metal band Jack Starr's Burning Starr.  Released in 1986 by the Canadian label Napalm Records. Proto-prog (short for "proto-progressive") is the first wave of British progressive rock musicians who branched from psychedelia or the advanced music that slightly predates the full-fledged prog era.  Progressive rock (originally "progressive pop") evolved from psychedelic/acid rock music, specifically a strain of classical/symphonic rock led by the Nice, Procol Harum, and the Moody Blues.  Proto-prog musicians harnessed modern classical and other genres usually outside of traditional rock influences, longer and more complicated compositions, interconnected songs as medley, and studio composition. This is a list of rock music genres consisting of subgenres of popular music that have roots in 1940s' and 1950s' rock and roll, and which developed into a distinct identity as rock music in the 1960s, particularly in the United Kingdom and the United States.  By the late 1960s, a number of identifiable rock music subgenres had emerged, including hybrids like blues rock, folk rock, country rock, and jazz-rock fusion, many of which contributed to the development of psychedelic rock influenced by the counter-cultural psychedelic scene.  New genres that emerged from this scene included progressive rock, which extended the artistic elements; glam rock, which highlighted showmanship and visual style; and the diverse and enduring major subgenre of heavy metal, which emphasized volume, power, and speed.  In the second half of the 1970s, punk rock both intensified and reacted against some of these trends to produce a raw, energetic form of music characterized by overt political and social critiques.  Punk was an influence into the 1980s on the subsequent development of other subgenres, including new wave, post-punk and eventually the alternative rock movement.  From the 1990s alternative rock began to dominate rock music and break through into the mainstream in the form of grunge, Britpop, and indie rock.  Further fusion subgenres have since emerged as well as conscious attempts to revisit rock's history. Bardo Pond are an American psychedelic rock band formed in 1991, and who are currently signed to London-based label Fire Records.  The current members are Michael Gibbons (guitar), John Gibbons (guitar), Isobel Sollenberger (flute and vocals), Clint Takeda (bass guitar) and Jason Kourkounis (drums).  Bardo Pond's music is often classified as space rock, acid rock, post-rock, shoegazing, noise or psychedelic rock.  Some Bardo Pond album titles have been derived from the names of esoteric psychedelic substances.  Their sound has been likened to Pink Floyd, Spacemen 3 and My Bloody Valentine amongst others. Vincebus Eruptum ( ; pseudo-Latin) is the debut studio album by American rock band Blue Cheer.  Released on January 16, 1968, the album features a heavy-thunderous blues sound, which would later be known as heavy metal.  It also contains elements of acid rock, grunge, experimental rock, blues rock, stoner rock, and garage rock.  A commercial and critical success, "Vincebus Eruptum" peaked at number 11 on the "Billboard" 200 albums chart and spawned the top-20 hit cover of Eddie Cochran's "Summertime Blues".  Being an example of hard rock, it is also lauded as one of the first heavy metal albums. Blues rock is a fusion genre combining elements of blues and rock.  It is mostly an electric ensemble-style music with instrumentation similar to electric blues and rock: electric guitar, electric bass, and drums, often with Hammond organ.  From its beginnings in the early- to mid-1960s, blues rock has gone through several stylistic shifts and along the way it inspired and influenced hard rock, Southern rock, and early heavy metal.  Blues rock continues to be an influence in the 2010s, with performances and recordings by popular artists.
