"Live from Lincoln Center" celebrates jazz trumpeter Louis Armstrong, his New Orleans roots and his music on PBS Wednesday, Dec. 13, at 8 p.m. The two-hour program with Wynton Marsalis and guest artists with the Lincoln Center Jazz Orchestra is part of a 13-month focus on Armstrong and his contributions to jazz. Beverly Sills is the host of "Armstrong When the Saints Go Marching In." Joining Marsalis and the orchestra are special guests Bob Wilber, Lucien Barbarin and Don Vappie. The program will explore Armstrong originals, songs closely associated with Armstrong, and other classic tunes from the era in which he came of age the 1920s. "Louis Armstrong took the spirit of jazz and brought it around the world," Marsalis says. "He internationalized the feeling of jazz and he universalized it in artistic terms." Known as Satchmo for most of his professional life, Armstrong is renowned as both the first great instrumental soloist in jazz and the father of jazz singing. From his early days playing in New Orleans streets and clubs to his concerts around the world, Armstrong was an international ambassador of goodwill. Although he claimed to have been born July 4, 1900, he was actually born Aug. 4, 1901. In honor of both dates, Jazz at Lincoln Center is celebrating 100 Years of Armstrong with events continuing through Aug. 4 next year. "Live from Lincoln Center" is the only series of live broadcast performances on American television today.
