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.
Both artists have rich histories as thriving collaborators.
