With endless three-part harmonies at its disposal, Pearl and the Beard is a folksy pop trio with a flair for lovely acoustic Americana. Members Jocelyn MacKenzie, Emily Hope Price and Jeremy Styles each convey a unique vocal style, influence and vision, with the help of cello, glockenspiel, non-traditional drums, accordion and guitar.

Pearl and the Beard's 2011 album Killing the Darlings has been charming fans and critics since last spring. Given the trio's tremendous chemistry and charm, it looks primed to build on that buzz in 2012.

It wasn't the fast lane to success for The Black Keys. In fact, the cover of the band's new album El Camino is a convenient reminder of that. The old, beat-up van featured on the front of the Akron duo's latest record is the actual vehicle the group used to tour in its early days. From then until now, The Black Keys' members have earned countless fans through rigorous touring and a strong body of work in the studio.

Considered one of the fathers of electronic music, British new-wave auteur Gary Numan has been releasing studio albums since the '70s. The man behind the classic hit "Cars" has influenced scores of musicians over the years, including Nine Inch Nails, David Bowie, Beck and many others.

The only aspect of Tinariwen more urgent and heartbreakingly human than its unique blend of electric rock and North African traditional music is its story. Tinariwen's members fought as rebels in Mali to protect their land and the Tuareg people, and out of the rebel camps formed a counterculture — and a rock band.

Shelby Lynne has been recording for more than two decades, but has never stopped evolving. Her music is powerful because it feels heartfelt and entirely hers; she's moved from label to label, style to style, but has always kept her individuality. The first decade of her career has been all about that movement, and now she's in a great rhythm.

In "Poor Moon," his recent release under the moniker Hiss Golden Messenger, MC Taylor revels in the classic simplicity of old-school folk. His waltz-y ballad "Blue Country Mystic" is a prime example of how Taylor blends the tried-and-true methods of home-grown bluegrass with the catchiness of contemporary indie folk. "Super Blue (Two Days Clean)" is a country-infused dance number that showcases his understanding of the folk tradition as history that lives, grows and moves its audience in deep, unpredictable ways.

The Head and the Heart was formed after five twentysomethings met at an open mic night in Seattle.

"None of us knew each other beforehand," recalls singer Josiah Johnson. "I just happened to go to the same open mic. [Jonathan Russell] played some songs and I played some songs, then we started talking and hanging out."

Looking at Andrew Mayer Cohen in his Buddy Holly glasses, styled like Michael Buble's little brother, he could easily be construed as another poppy heart-breaker. But this young soul man from Detroit is actually a rising hip-hop and R&B artist. Known as Mayer Hawthorne in the music world, he's built an impressive reputation for himself.

Friends since college, guitarist and vocalist Israel Nebeker and drummer Ryan Dobrowski are the essence of Portland's Blind Pilot. From the beginning, their minimalist folk-rock sound has revolved around simple melodies, sparse drumming and warm vocals.

Blitzen Trapper's rise to fame has been nontraditional, to say the least. According to frontman Eric Earley, who writes most of its music, the band was homeless up through the 2008 tour for its breakout fourth album, Furr. This was a year after the "reluctant success," as Earley called it, of Wild Mountain Nation.
