On this Brazilian master's 1978 self-titled album, you'd swear that a young Ben Harper is staring at you from the cover. Ramalho's sound is equally timeless, influencing contemporary psych-folk and jam bands alike. Fusing Latin percussion, crisply strummed acoustic guitar, loping bass and trippy psych-rock flourishes, his songs are both intensely personal and socially conscious. Even if your Portuguese is rusty—or non-existent—his emotive vocals cut to the heart, whether he's singing about his late grandfather or providing the theme to a popular Brazilian soap opera.
