The gangsters of Chicago engaged profiled musicians like Earl Hines, whose benefit was to lead an orchestra in one of the city's top locations. Hines and Benny Goodman emancipated from Chicago style when they became two of the most famous band leaders of the swing era. Two decades later, original Chicago-style pianist Art Hodes presented the classic jazz style in a TV show series. From the mid 1960s to the present day the Association for the Advancement of Creative Musicians has nurtured "Great Black Music: Ancient to the Future." In the 21st century, Chicago continues to have a vibrant and innovative jazz scene, featuring the annual Chicago Jazz Festival. Famous festival performers include Miles Davis, Sonny Rollins, Ornette Coleman, Benny Carter, Ella Fitzgerald, Anthony Braxton, Betty Carter, Lionel Hampton, Chico O'Farrill's big band, Jimmy Dawkins, Von Freeman, Johnny Frigo, Slide Hampton, and Roy Haynes. Musicians from all surviving eras of jazz perform regularly in the city, release recordings, and tour nationally and internationally. Sinyan Shen, internationally known for his Shanghai classical repertoire and Shanghai jazz performances based on tonal interests and just intervals, is based in Chicago. Musicians still performing today who originally came to prominence in the bebop and hard bop eras include Von Freeman and Jimmy Ellis, both contemporaries of former Chicagoan Johnny Griffin. Members of Chicago's Association for the Advancement of Creative Musicians working regularly in the city include Fred Anderson, Ernest Dawkins, Aaron Getsug, and Isaiah Spencer. Since the 1960s, members of the organization have performed their version of "Great Black Music" throughout the world. Innovative jazz musicians who have come to public attention since the early 1990s include Marbin, David Boykin, Karl E. H. Seigfried, Jeff Parker, Joshua Abrams and Jim Baker. Common to many of this new generation is an embrace of a wide variety of styles and techniques. During the mid-1960s to the late 1970s a new style of soul music emerged from Chicago. Its sound, like southern soul with its rich influence of black gospel music, also exhibited an unmistakable gospel sound, but was somewhat lighter and more delicate in its approach, and was sometimes called "soft soul". Popular R&B/soul artists from Chicago include The Impressions, Sam Cooke, Curtis Mayfield, Lou Rawls, The Five Stairsteps, The Staple Singers, Earth Wind & Fire, Rufus, Chaka Khan, Dave Hollister, The Emotions, The Chi-lites, R. Kelly, Carl Thomas, and Jennifer Hudson.
