High Quality Content by WIKIPEDIA articles! Youth Dub is a bonus disc released in conjunction with Matisyahu`s second studio album Youth. Both discs were released on March 7, 2006). Youth Dub is included with some copies of Youth and is available as a limited edition, stand-alone album. Producer Bill Laswell made a King Tubby style dub remix of Youth, adding effects and bringing to the fore the music of the backing band Roots Tonic rather than Matisyahu`s vocals. Laswell was so impressed with the band that he invited them back into his studio and teamed up for an all-instrumental dub album, Roots Tonic meets Bill Laswell.
