Antigen is a collaboration of House heavyweights Gomi and Hani. This song originally came out in 2005, however, some brand new mixes have been completed. The 2005 versions have been remastered. They are delightful throwbacks to the heyday of Disco from the orchestra to the bassline to Andrea Martin's warm, divatastic vocals. The new Extra Sauce mixes are deeper and softer. They lose much of the Disco flavor of the earlier versions. These are great as well.
