Dozens of major rock acts dabbled in dance during the '80s and '90s, influenced indirectly by the times and the technology or directly by the funk, Philly soul, and disco that had ruled the R&B roost during the '70s. The genesis for dance-rock was the mid-'70s, when the Rolling Stones, David Bowie, Rod Stewart, and Queen all flirted (at one time or another) with the simpler rhythms and heavy groove of funk and disco. Then, influenced by varied sources (including most of the above), many of the biggest alternative crossover acts of the '80s -- Duran Duran, INXS, Pet Shop Boys, ABC, Eurythmics, the B-52's, Depeche Mode, New Order -- fused dance and rock in some manner.
