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.

This segment, from Sept. 18, is part of our Best Of 2013 series, in which we revisit some of our most memorable interviews and performances of the year.

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.
