World Cafe on KRVS

Joining us in the studio for hour two of Tuesday's World Cafe is the Los Angeles band He's My Brother, She's My Sister. As the name implies, lead vocalists Robert and Rachel Kolar are indeed siblings.

In hour one of Tuesday's installment of World Cafe, we talk with Elvis Costello and The Roots' powerhouse drummer Ahmir "?uestlove" Thompson about how they met and came to utilize hip-hop techniques to make a non-hip-hop record. Costello and The Roots unveiled their collaborative album Wise Up Ghost last week — it's a project they'd made in semi-secrecy.

Musically speaking, we travel to Iceland for Monday's installment of World Cafe: Next. Our featured artist is Ásgeir, a 21-year-old singer-songwriter who's on his way to making history. After releasing his debut album (In the Silence) in his homeland last year, the singer has the best-selling and fastest-selling debut album ever in Iceland.

In this installment of Vintage Cafe, we revisit Ray LaMontagne and The Pariah Dogs' performance from Oct. 8, 2010.

Singer-songwriter Jack Johnson recently released his sixth album of breezy, easygoing songs: From Here to Now to You finds him returning to more acoustic arrangements after 2010's To the Sea, which featured more instrumental variations, including electric guitars.

In this World Cafe session, Johnson credits much of his success to his wife, and dedicates a couple of songs to their relationship. The singer also discusses his Hawaiian home and the influence of the indigenous slack-key guitar culture on his style.
