Each time I see James Blake and his band perform, I feel the extreme rush of hearing something for the very first time. The sound is sharp and visceral; it oddly vibrates the hair on my arms and, at moments of extreme bass, gets me feeling claustrophobic before the inevitable release when Blake sings. It's hopeful, mournful, always thoughtful.

There's something endearing, old-timey and almost vaudevillian about Buddy Miller and Jim Lauderdale — even the way they bill themselves as "Buddy and Jim." Both veteran musicians are in love with country music in all its many forms and influences; their music incorporates the blues and bluegrass, rock 'n' roll and a good deal of craft.

In the seven months since Gary Clark, Jr. released his major label debut, Blak and Blu, he's played for the President at the White House with Mick Jagger and blues legend B.B.

How can music be happy and sad at the same time? Listen to Olafur Arnalds and you'll hear it. Depending on your mood, the tone changes, and a song that may have been uplifting one day sounds like an elegy the next. It's spacious, undeniably beautiful work. Much of the music performed in this concert, recorded on April 18 at (Le) Poisson Rouge in New York City, is drawn from the Icelandic musician's recent album For Now I Am Winter.

A is for Alpine and it's also the name of Alpine's debut album. Alpine is a six-piece ensemble from Australia with an airy sound led by singers Phoebe Baker and Lou James. The group's album, A is for Alpine, has been out in their home since 2012, but it arrives in the U.S. on May 21.

The Handsome Family, the wife and husband duo of Rennie Sparks (vocals, bass and banjo) and Brett Sparks (vocals, guitar and keyboards), love telling stories, and they've been doing it in song for 20 years. A new album, Wilderness, is out May 14, and "Woodpecker," a song from the album, tells a fascinating tale about Mary Sweeney, who, in the 1890's, was known as the Wisconsin Window Smasher.

"'The World Is Changing' is groove with a message." That quote, a pretty good summary of the music of Femi Kuti in just nine words, comes from Juan Gélas, the creative director of a new video for Kuti's new song. Femi Kuti is a saxophonist, trumpeter, keyboard player and singer and songwriter. The son of legendary afrobeat musician Fela Kuti, he carries on the tradition of mixing Nigerian beats along with jazz and a healthy dose of politics. Juan Gélas says, "Femi Kuti continues to be a leading protest artist out of modern Africa and his voice talks to us all."

Pete Lawrie Winfield makes music as Until The Ribbon Breaks, stark music with a good deep vibe; Massive Attack or James Blake would be good touchstones. Until The Ribbon Breaks doesn't have much music out yet, but "Pressure," a new song, has urgency. "'Pressure' was written at a time of upheaval and transition for me," Winfield writes. "I was sleeping at my studio and had no idea what I was going to do next.

In a small, packed Washington, D.C., living room late one December night, I heard a cacophony of horns, keys, drums and guitars that simply floored me. It was brash, zany, brainy, scary and danceable. At the end of a long year of amazing live music, this would turn out to be one of the most memorable concerts I'd seen.

Music videos are like funny math, where 1+1=3. That is, images have a meaning on their own, music has a meaning when you listen to it alone, but put images and music together and something new is born. 1+1=3. Try it randomly: put on a piece of music and watch a cartoon or an old movie ... people did it famously with The Dark Side of the Moon and The Wizard of Oz.

It was probably the best performance piece I've seen in more than a decade. Specific Ocean, a piece by the dance troupe/rock band People Get Ready, which I saw at the New York Live Arts theater in the fall, was a model for the ways musicians can break from the standard, sometimes boring, format of playing on a stage. Some of the songs from Specific Ocean ended up on the group's 2012 self-titled album. Now there's a video, a documentation of that amazing New York performance, featuring the song "Middle Name."

There was a "fire in the belly" feel when Brainstorm took the stage at TenOak in Austin, Texas, during the South by Southwest music festival this past March. In its best moments, the trio from Portland, Ore., has an edge that embodies both African highlife guitar and the sounds of late-'70s post-punk a la Gang of Four.

Bands with big ideas work well at the Tiny Desk. Efterklang is a Danish group whose recent album Piramida took its members to an abandoned mining town between the North Pole and Norway. There, they recorded sounds of empty oil tanks, old pianos and pretty much anything they could strike or record.

The Postal Service was a band for a generation — the soundtrack to romance, tears and friendship. More than a million people bought its first album, 2003's Give Up, then waited anxiously for a follow-up that never arrived.

Playing a free concert comes with risks. Sure, more people will show up, but they may care less about who's on stage than they do about catching up with friends; ironically, it often means the band has to work harder to win over the crowd. Seattle's Ivan & Alyosha did just that on the final night of the 2013 South by Southwest music festival, at a club called TenOak in Austin, Texas.
