Recently, i started listening to Hallmark '87. ATRIUM is the best mallsoft album in my opinion. :D I also like Computer Dreams and Infinity Frequencies. Their music is so mysterious,foggy and full of emotions :D
Undoubtedly, ESPRIT 空想 is my favorite vaporwave artist. I would say George Clanton(who is essentially ESPRIT 空想), however music that has been released under his real name is not necessarily the most 'vaporwave' in style. I say this cautiously because of the negative connotations that the word pop might have, but I would say it's kind of like pop vaporwave. Nonetheless I still enjoy it very much and have nothing but good to say about his music.
