456132015 is the EP by Americandub-reggae band De Facto, released on 1 March 2001 through Grand Royal in Europe only. It's often considered as the band's first official release, as their debut De Facto was only available as a very limited pressing.
The EP, recorded by Robert Carranza and produced and mixed by Mario Caldato Jr., is notable for its clean production and more polished sound compared to other De Facto recordings, mostly made at members' home studios. It is also the band's most vocal-heavy release, and the only one to feature Cedric Bixler-Zavala lead vocals (on "120E7"). Alternate versions of "120E7" and "Vesica Pisces" would be later released on De Facto's second LP, Légende du Scorpion à Quatre Queues.
The title is a coded message using numbers and the corresponding letter of the English alphabet; it spells "DEFACTO" (4=D, 5=E, 6=F, 1=A, 3=C, 20=T, 15=O).
