Symmetry is the twenty-third studio album by Canadian rock band Saga. It was released on March 12, 2021. It contains acoustic versions of previously released songs, some in the form of medleys or augmented with new interludes. The idea originated on the 40th anniversary tour in 2017, where the band would perform acoustically as their own support band "Pockets". The artwork has its roots in the 2017 tour, too, where a similar image (featuring a tree in the middle of a library, overlooked by the band's insect mascot) was used as a large backdrop for the acoustic section of the shows.
