Stone Rollin' is the fourth studio album by American R&B singer, songwriter, and producer Raphael Saadiq. It was released on March 25, 2011, by Columbia Records and recorded at Saadiq's studio Blakesee Recording Company in Los Angeles over the course of a year. 　　Saadiq was inspired by the loud, raw quality of his concert performances in support of the 2008 album The Way I See It, leading him to pursue a grittier, more aggressive sound for Stone Rollin'. Joined again by sound engineer Charles Brungardt, he expanded on its predecessor's traditional soul music style with sounds from rhythm and blues, rock, funk, blues, and psychedelic music. Most of the album's instrumentation was played by Saadiq, including the prominently featured Mellotron keyboard. With the help of arranger Paul Riser and engineer Gerry Brown, the singer also incorporated string and orchestral arrangements to the songs. 　　A widespread critical success, Stone Rollin' was deemed by some reviewers as Saadiq's best work and noted for its stylistic breadth, groove-based compositions, and varied subject matter. It also became the singer's highest-charting album in the United States, reaching number 14 on the Billboard 200. He supported the release with a concert tour from March to August 2011.
