’Hot Thoughts’’ is the bravest, most sonically inventive work of Spoon’s career. With all due respect to earlier efforts that have made the quintet both critically acclaimed and a commercial contender, preconceptions about this band are about to be obliterated. That’s not to say ‘Hot Thoughts’ doesn’t have a requisite supply of infectious earworms but there’s a lyrical bent that’s as carnal as it’s crafty, and a newfound sense of sonic exploration that results in the genresmasher Spoon have flirted with in the past but not fully consummated.
