Continuing to perform, Matisyahu assembled a backing band consisting of guitarist Aaron Dugan, bassist Josh Werner, and drummer Jonah David. The group recorded Shake Off the Dust...Arise, which was released by JDub Records in 2004. While touring in support of the album, Matisyahu recorded one of his February 2005 concerts and released the material as Live at Stubb's, which was issued in April courtesy of Or Music before getting picked up for national distribution by Epic Records. Epic reissued it on August 23, 2005, as Matisyahu toured around the country and prepared a second studio album with producer Bill Laswell. The final product, Youth, appeared in March 2006 and was nominated for a Grammy in the category of Best Reggae Album. A simultaneously released dub version of the album was made available to mail-order customers.
Meanwhile, Matisyahu's backing musicians chose to release additional material on their own, adopting the name Roots Tonic for the side project. Roots Tonic Meets Bill Laswell marked the group's debut in May 2006, and by the end of the year the EP/DVD combo No Place to Be was also released. Jonah David dropped out of the band in June 2007, however, and Roots Tonic effectively disbanded, despite the enlistment of replacement drummer Skoota Warner. The entire group (sans David) turned its focus back to Matisyahu instead, and Light marked the singer's third LP upon its release in August 2009. Two years later, Live at Stubb's, Vol. 2 would appear, this time with a companion DVD release. In late 2011, the singer posted a picture with a shaved head and payes cut with the caption, "No more Chassidic reggae superstar." As such, his 2012 effort Spark Seeker was more secular pop, and was produced by Kool Kojak, who had previously worked with Keha and Nicki Minaj. William Ruhlmann, Rovi
