Days after Michael Jackson died in 2009, DJ Dredd hosted “Remember the Time,” a tribute at Liv that featured nothing but Michael Jackson, Jackson 5 and Jacksons music for five hours while remixed videos played on large screens. People danced while singing along (loudly) and smiling broadly, many tearing up and hugging friends. It was cathartic. It was amazing. Dredd is bringing his bag of rare tracks by Michael Jackson, his family and friends to the 9:30 Club for Michael Jackson’s Birthday Celebration. We’re willing to bet the roof will be raised higher here than anywhere else in town, thanks to one of the city’s top DJs, who can turn any venue into an old-school house party, and some of the finest pop music ever recorded.
