Megaritual is the fifth and final album in the series initiated and recorded by Omar Rodriguez Lopez in Amsterdam in 2005. Committed to tape in 2006 and mixed the following year, the album features nine instrumental tracks performed solely by Rodriguez-Lopez and his brother, Marcel Rodriguez-Lopez. Omar claims Megaritual was "an exercise to be closer to my brother."

The first three tracks, and their titles, all flow together to form one 10-minute piece.
