Mash-up master Girl Talk — AKA biomedical engineer Gregg Gillis — drops his fifth album of ADD mixes with “All Day.” By now, Gillis is a veritable musical chemist who creates genre-bending concoctions bringing together artists like Outkast and Nirvana Lil Wayne and New Order, and Radiohead and Ol’ Dirty Bastard. The combinations are captivating, but “All Day” falls slightly short of the electricity and climactic moments of his last release, “Feed the Animals.”
