On their 1968 album Living the Blues, Canned Heat set some kind of jam-endurance record with the live 40-minute track “Refried Hockey Boogie.” The New York quartet Endless Boogie go even further — 79 minutes — on their fantastic, note-perfect update of electric-blues drone and railroad rhythm, Focus Level (No Quarter). The album is divided into 10 so-to-speak songs, such as the Can-like chug “The Manly Vibe” and “Executive Focus,” a dead ringer for a 1971 Pink Fairies wig-out. But the cumulative effect of the hog-sneeze distortion, twin-guitar skirmishes and John Lee Hooker-style chooglin’ is nonstop stoner-rock delight. The vocals are cartoon-demon yowling, but the rest is as authentic as my old Groundhogs LPs. Singer-guitarist Top Dollar (the band members use pseudonyms) is also a renowned rare-record dealer — real name Paul Major — who has now made an album as freaky as those he sells.
