The Rolling Stones [SEP] Introduction
Since the 1990s, new material has been less frequent. Despite this, the Rolling Stones continue to be a huge attraction on the live circuit. By 2007, the band had four of the top five highest-grossing concert tours of all time: Voodoo Lounge Tour (1994–95), Bridges to Babylon Tour (1997–98), Licks Tour (2002–03) and A Bigger Bang (2005–07). In 2012, the band celebrated their 50th anniversary. Their latest album, "Blue & Lonesome" (2016), became their twelfth UK number-one album. The group continues to sell out venues, with their recent No Filter Tour running for two years and concluding in August 2019.
