John Lee Hooker's albums are sprinkled with obscure examples of his elastic sense of time. His manic foot stomps and clustered licks nearly tear apart the boogie raver “Roll ‘N' Roll,” while the country-blues cut “Turn Over a New Leaf” comes riddled with heaving tempo shifts. The holiday tune “Blues for Christmas” offers no respite, as Hooker almost trips up the band with his staggered beat and languorous moans.
