For his latest Columbia Jazz recording, tenor saxophonist David Sánchez revisits his roots. The results? Obsésion, a sizzling hot and coolly lush collection of Latin American classics from Cuba, Brazil and Puerto Rico. Sánchez calls the disc the most important of his young career. "There are plenty of albums of jazz standards," he says. "So why not record a CD of Latin standards? It is a retelling of who I am and it is always easier to tell a story as an insider."	Acoustic guitarist Peter White takes a break from recording and offers a glimpse from the studio of what to expect on his sophomore contemporary jazz CD for Columbia. White describes the work-in-progress as "monster grooves punctuated by acoustic interludes" and announces that a very special saxophonist makes a guest appearance. He calls the experience "a thrill beyond words." White also provides insights on how he approaches working on a new project.	Miles Davis recorded the bulk of his most important music for Columbia. Producer Bob Belden, who is spearheading the Columbia/Legacy reissue series of the legendary trumpeter's catalog, checks in with a review of the latest releases as well as a preview of what's slated for the near future. The vault keeper of the Davis archives also celebrates the new Columbia Jazz project, Panthalassa: The Music of Miles Davis 1969-1974, a reconstruction and modern mix translation of music from Davis' post-'67 electric period, produced by Bill Laswell.	Meet tenor saxophonist David S. Ware, the newest member of the Columbia Jazz roster. Influenced by saxophone titans John Coltrane and Sonny Rollins, Ware makes his label debut with Go See the World, an exhilarating collection of new compositions grounded in the tradition of the passionate free style of the '60s. "We're like the Marines coming in to create a platform for the spirit of exploration and freedom in music," says Ware, who Branford Marsalis champions as "a wellspring of expression."
