Somehow the will of music-industry titans and the whims of music-consumer taste have converged, launching Australia’s Tame Impala as one of the big-festival psych-rock bands of the mid 2010s. Their debut album Innerspeaker introduced mastermind guitarist/vocalist Kevin Parker as an ambitious auteur prone to firmament-filling, heavily FX’d guitars and vocals that take John Lennon’s in “#9 Dream” to the heavens. Parker’s managed the rare feat of making rock songs that sprawl and possess memorable hooks while not ignoring the crowd-pleasing power of prominent, funky beats. Ironic that the guy who wrote the lovely “Solitude Is Bliss” now performs before several thousand people per show. by Dave Segal
