Burdon and the group returned in April 1968 with The Twain Shall Meet, continuing their psychedelic journey. "Monterey" chronicled the previous summer's seminal festival while "Sky Pilot" reflected the growing anti-war sentiment as the Vietnam Conflict escalated. Steeped in a dense, layered sound full of electric guitars, sitars, strings, brass and washes of phased vocals, the album served notice that Burdon and company were totally in-step with America's youth movement. From blues revivalists to cultural torchbearers in four short years? Believe it!
