"Aesthetic of the Day: Depthcore / Metalheart / Trendwhore (~1998-2004)
Thought I’d start doing some posts on various aesthetics I’ve been studying since starting my exploration of Y2K four years ago. Metalheart, named for the 2001 book of the same name cataloging the work of Swedish designers Andreas Lindholm and Anders F. Ronnblom, is a visually complex and heavily digital aesthetic popular in the very late 90s and early 2000s. Its precursors include experimental deconstructivist works of designers like Zaha Hadid, the loud and expressive graphics used in rave flyers of the era, and designs by firms ATTIK and Me Company. " Interesting to note because i do remember this being common in the Y2K era.
