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.

Neko Case's new album, The Worse Things Get, The Harder I Fight, The Harder I Fight, The More I Love You, expands upon the fiercely intelligent singer-songwriter's gifts for music that's both innately infectious and rooted in intense, accessible emotions.

Soulful singer-songwriter Jessie Ware is far from the first vocalist to make the transition from backing vocals to center stage; Sheryl Crow once backed Michael Jackson, after all. But the Londoner has made the leap with tremendous success in her own right.

This week's World Cafe: Next artist is the Kansas band Moreland & Arbuckle, whose members play blues-drenched roots-rock. On their fifth album, 7 Cities, they've adopted the loose theme of the explorer Coronado's search for the seven cities of gold — which, not so coincidentally, took the conquistador right into their home territory.

After working together for more than a decade, the members of Stockholm's Shout Out Louds continue to make lush, highly melodic pop music. The product of a year and a half of tinkering, their recent Optica is significantly lighter-sounding than its predecessors.

On this installment of World Cafe, hear the group discuss how it navigated new musical experiments on the album, and how all of its members finally came to agree on how Optica should sound.

Pete Yorn has long had a way with hooky rock songs, so it was easy for him to connect with fellow L.A. musician J.D. King over a mutual love for '60s music. The two first started recording together just for fun, blending folk-rock and subtle psychedelia into a joint project they call The Olms.

When Telekinesis' Michael Benjamin Lerner plays live, he sings from behind his drum set, but he plays almost all the instruments on his albums. The power-pop multi-instrumentalist recorded his latest record, Dormarion, at Spoon drummer Jim Eno's house — fittingly located on Dormarion Lane.

Sam Amidon grew up surrounded by music, from playing fiddle with his parents in Vermont to finding a best friend in musician and arranger Thomas Bartlett (a.k.a. Doveman).

Rose Windows' debut album, The Sun Dogs, is steeped in '60s classic rock, recalling the heavy organ sounds of The Doors and the folk-infused flutes of Traffic. Formed in 2010 by songwriter Chris Cheveyo, the Seattle septet signed a label deal earlier this year, then put together an album that's layered with Middle Eastern influences.

Hear two songs from The Sun Dogs, a mellow combination of psychedelic folk and blues-rock instrumentation.
