The Omar Rodriguez Lopez Group (often referred to by its acronym ORLG) is an American experimental rock band, and the main side project of Omar Rodríguez-López. Featuring an ever-changing lineup of musicians alongside Rodriguez-Lopez, the group is most often a live entity to perform the various outlets of his solo music aside from the Mars Volta. After the dissolution of the Mars Volta in 2012, Omar completed a few more solo records until 2013 before deciding to pursue only collaborative efforts with groups At the Drive-In, Bosnian Rainbows, Antemasque, and Crystal Fairy.
