Groove Over Dose, known by the acronym g.o.d, is a South Korean boy band formed by SidusHQ. Debuting in 1999, the group became one of the most popular boy bands of the early 2000s in South Korea. The members had gone on to solo careers in the entertainment industry after indefinitely discontinuing group activity in 2005 following the departure of a member. However, they regrouped as a quintet and made a comeback in July 2014. Although the group is largely known for their "story telling" lyrical style and signature blend of R&B and rap, their repertoire features a diverse array of genres ranging from hip hop to funk.
