Earlier we reported that rapper H-Eugene would be making his comeback onto the k-pop scene under the new duo H2. Now H2 has released their first digital single & music video for Heartattack! As mentioned before, H-Eugene's counterpart is a female singer named Han Soo Yeon and her vocals are insanely crazy. This unlikely fusion of two elements results in one amazing piece of music. H-Eugene said, "From picking my vocal partner to creating the track, I really put my heart into the project. I promise to put on great live performances so please show Heartattack a lot of love." Like he said, you can truly feel that he put his all into this project and can even feel the raw emotion in the track. Check it out for yourself below! http://www.youtube.com/watch?v=yrKdFJqVAP8 H2 will be making their live debut on the 7th through Music Bank and on the 9th through Inkigayo.
