The Under Cover Sessions is a five-track EP by American heavy metal band Ill Niño, released on November 7, 2006, via Cement Shoes Records.

[3] It is their first release on the label, after departing Roadrunner Records in June 2006.

The EP was the first to feature Diego Verduzco on guitar (originally in Odum), as a stand-in for Jardel Paisante, who had not been a part of the group since the spring of 2006.

Verduzco was also on the photo shoots of Ill Niño for the EP, so many fans saw him as a full-time replacement for Jardel Paisante.

It sold 1,300 copies during its first week of release.
