Breakthru is the self-released debut album by American singer-songwriter Antoniette Costa. It was released on her label L.I.P. Label 14 on March 1, 2005.
The album exhibits Costa's R&B and soul tendencies as a singer-songwriter. Some of the 12 tracks are piano ballads, while others are accompanied by a band. The album was dedicated to her recently deceased aunt, and featured 12 songs that had been written from middle-school to college. In honor of her aunt, who was an avid supporter of education, Costa donated a percentage of the album sales to the Rosalita Costa-Clark School Fund in Pittsburgh.
Costa independently released the album on March 1, 2005, on her own record label L.I.P. Label 14. The album ranked No. 1 on Amazon's Early Adopter Indie Music Chart and No. 69 on the Early Adopter All Music Chart. It also led to Costa's future collaborations with members of The Roots.
