The blues as hypnotic mantra music reached a sublime peak on Endless Boogie. Working with a band of rock ’n’ roll longhairs, John Lee Hooker surrounds his deep groans and singularly fractured grooves with hazy psychedelia, including watery electric piano on “Kick Hit 4 Hit Kix U (Blues for Jimi and Janis)” and talking wah-wah on “Standin’ At the Crossroads.” The album’s clutch of open-ended jams, including the smoking, reverb-spiked “Endless Boogie, Pts. 27 & 28,” helps lend these recordings a loose, late-night vibe.
