Edward Sharpe & The Magnetic Zeros are full of big love and big hooks—something they've learned from fellow free spirits like The Mamas & The Papas and uplifting orchestral-pop collective The Polyphonic Spree. But the band also explore other sides of '60s hippiedom, channeling the Grateful Dead's dreamy psych country and The Doors' slithery, paranoid organ rock in their lush, philosophically charged anthems.
