<P> At the 2011 Pre-Grammy Gala in Los Angeles, Kelly performed a medley of hits including "Happy People", "When a Woman's Fed Up" and "Bump N' Grind". Ann Powers of the Los Angeles Times wrote "Kelly is a single - bound kind of leaper who dips into everything from soft porn to opera in his music . His supreme chutzpah, a quality he shares with Streisand, allows him to feel secure within pop's traditions while taking them wherever he pleases . He made Davis' musical program, which at times got lost amid the chatter of the A-list crowd, come alive . It was all so simple then: an instant when one of pop's key traditional elements, that determination to wow, took on new dimension in the hands of an expert ." </P> <P> In March 2011, Kelly was named the #1 R&B artist of the last 25 years by Billboard . In his career Kelly has amassed 35 top 10 hits and 11 #1 hits on the R&B / Hip - Hop Songs chart . </P> <P> On July 19, 2011, Kelly was rushed to the Northwestern Memorial Hospital in Chicago to undergo emergency throat surgery .

Johnny Gourzong, Sumfest Productions executive director, also commented, saying, "We are truly going to miss his presence on the festival ." On July 20, 2011, in a press release, representatives for R. Kelly explained that he was rushed to the hospital to drain an abscess on one of his tonsils and "will be laid up for an indefinite amount of time". Shortly after, Kelly tweeted fans "I WILL BE BACK!" he promised and "I'd like to thank everybody for their love, concern and support ." On July 21, 2011, Kelly's spokesman, Allan Mayer, reported that Kelly was released from Northwestern Memorial Hospital in Chicago and is recuperating at home . It was not immediately clear when Kelly might be well enough to resume performing . On July 21, 2011, in a video message to fans, Kelly spoke out for the first time since throat surgery and reassured his fans that he's doing well . He said "Yo what's up, y'all, it's your boy Kellz, fresh out the hospital . Just want to say thanks to my fans for supporting me . I want to say thanks to all the prayer warriors out there for supporting me ." </P> <P> On September 23, 2011, Variety confirmed that Kelly has signed on to write original music for the Sparkle soundtrack . On April 25, 2011, Director Salkim Akli was quoted saying, "Hopefully, R. Kelly will come on and do some of the music for the film . His latest music sounds like it came from a time period . Here's a guy who can write about a woman being a jeep to' I Believe I Can Fly' and he's an artist . Whether you like him or dislike him, I love artists, and I know that he will just go deep into it and come up with something unique ." </P>
