-屏住呼吸，侧耳倾听，‘I know it's your voice’ winner组合的主唱兼作词、作曲、制作乃意至演技活动并行的万能艺人姜昇润参与了《voice 4》的第二首OST《Your voice》。 《Voice 4》的新面孔，饰演韩宇宙的姜昇润参与演唱的《Your voice》是一首强烈的转播吉他声和强烈的演唱给人深刻印象的摇滚抒情曲， Intro独特的Arpegio Line仿佛代表了人物们动摇的心理状态一样，营造出奇妙的氛围。 再加上姜昇润富有色彩的声音，与前半段节制而又有号召力的声音相比，后半段表现出如爆发般的强烈感，进一步提升了观众对电视剧的投入度。 《Your voice》是ELMUSIC Publishing的内部制作团队"ELDORADO"所属作家们的作品，今后不仅是OST，歌曲、舞蹈、偶像、Solo等K-POP全能发展的他们的活动也令人期待。 [Credit]  OST by 뮤직그라운드 Executive Producer 김재곤 Coproducer 박재희 Office Director 박현정, 이지연 Album Designer 박민선 작사 bK (ELDORADO), 방지선, 어지혜 작곡 뉴찬스(ELDORADO), bK (ELDORADO) 편곡 뉴찬스(ELDORADO) Chorus by 강승윤, JDM (Machine II the Moon) Guitar by 정재필 All Midi Programming by 뉴찬스(New Chance) Recorded by 신성권 @ YG STUDIO Mixed by 임승현 @ Sync Entertainment Mastered by 전훈 @ Sonic Korea
