He needs to produce her full album. The production on her last release was very sub par, esp when compared to her earlier tracks. I feel like when she came out it was like "Cool, innovative and edgy." Then with her last release it was like "hmm..." The only explanation I can come up with is that she wanted to separate herself from being just another "trendy" artist and wanted to have a more "timeless vibe" attributed to her. Anyways, Zedd is very forward and modern with his production techniques and has such a lovely clean and powerful sound with still having a bit of tasteful edge. Him and Lucky Date should team up on the Gaga album, that would be ultimate in my opinion.
