Sinnravian drad music was a style of music popular among the Sinnravian people in the late 24th century. In 2376, one of the most popular composer/performers of drad was Blee Luu, who founded the "atonal minimalist" subgenre of the style.
Starfleet Lieutenant Nog was a fan of drad, as was Dr. Carol Abramowitz. However, most other humans and Nasats found it intolerable. Abramowitz's cabinmate on the USS da Vinci, P8 Blue, threatened to feed Abramowitz to her larvae if she continued to play the music in their shared quarters.

Nog, in turn, gave the recording to Captain Janna Demitrijian in return for the USS Sugihara's assistance in towing space station Empok Nor to the Bajor system. Demitrijian gave the recording to her son's Sinnravian girlfriend on the Canopus Planet. (SCE eBook: Cold Fusion)
According to popular opinion, Drad music contained some types of composition that would be difficult for some species to adapt to playing competently. Paul Stiles once compared the sense of wrongness of boarding an Undine bioship with how wrong it would strike him if there was a Vulcan drad band. (STO novel: The Needs of the Many)
