Both in their early 20s, First Aid Kit's Johanna and Klara Söderberg are already winning over listeners worldwide with their intricate, woodsy harmonizing. The Swedish duo's second album, The Lion's Roar, has already charted in Australia, Denmark, the U.K., Norway and Sweden.

The Philadelphia pop-rock band Dr. Dog has continued to get better since forming in the early 2000s. The group's seven albums of layered psychedelia are deeply influenced by the best of '60s pop, adding up to a sound that's both timeless and classic.

Kevn Kinney of Drivin N Cryin and Anton Fier of The Golden Palominos combine the twangy side of their respective rock bands for an album aptly titled A Good Country Mile. Through the '80s rock scene, Kinney and Fier became friends and collaborators, and the trend continues more than 20 years later.

The group combines hoarse vocals, dramatic riffs and electronic flourishes on its debut — available for free on Harriet's website, though probably not for long.

On Nada Surf's new album, The Stars Are Indifferent to Astronomy, the long-running band alternates between infectious optimism and sweet sadness. In spite of countless label changes, the group has remained remarkably consistent in its 20 years together: Blending good-natured affirmations with catchy pop-rock hooks, Nada Surf sounds like a bunch of fresh-faced kids, albeit unusually wise ones.

Formed by four Peruvian high-school friends in 2001, Novalima has been making traditional music sound sultry and modern ever since. In the past decade, the group has grown to a nine-piece band that's helping change the way the world thinks about world music.

After first coming together as a trio at Cardiff University in 2006, Los Campesinos! has blossomed into a septet with a reputation for lively indie-rock, in the spirit of everyone from Modest Mouse to Broken Social Scene to Belle and Sebastian. The generous joy in the Los Campesinos!
