Portugal. The Man is one of the more eclectic bands I've encountered. Their style is completely all over the place. They range from hard-driving rock, to mellow, simple acoustic folk songs. The modern music fan doesn't focus on only one genre, and neither does Portugal. The Man. "People Say (Acoustic)" is an acoustic version of one of their more popular songs, "People Say." It's found on their album The Majestic Majesty, which consists of acoustic covers of the songs found on The Satanic Satanist. "All My People"is a little bit more typical of their style, a catchy, somewhat psychedelic song that's definitely worth a listen.
Sounds like: The Black Keys, Tame Impala
