[앨범 소개] '허상'은 우리말이 아닌 한자어로, 쓸데없는 헛된 생각, 부질없는 생각을 의미하며 사랑에 빠져 행복해하던 날들을 이별 후에 다시금 떠올리며 과거에 머무르는 '나'의 모습을 음악으로 표현하였다. 총 4개의 각기 다른 에피소드를 가진 4개의 곡으로 구성되어 있으며, 이걸 듣는 모든 이들이 과거에 머무를지언정 '허상'으로나마 행복하면 좋겠다. 아티스트 ISHA(이샤)는 걸그룹 베리굿에서 고운으로 활동하며 아이돌로서의 활약하던 모습을 차근히 벗어던지며, 색다른 느낌의 여러 장르의 음악을 '이샤'만의 색깔로 다양히 표현하는 아티스트가 되고 있다.
