Hei’An is a post-progressive metal band from Slovenia, blending elements from a variety of different genres and subgenres in their music, including progressive metal-esque beats and rhythms, post-metal-esque chord progressions and ambiental parts, black metal-esque tremolos and blast beats, metalcore-esque choruses and riffs etc., while creating and cultivating their own unique sonic direction, packed with both intimacy and huge-sounding segments, putting the emotional value and impact of their music above all else.

The name Hei’An is a pseudonym for their frontman, bandleader and songwriter Matic Blagonič, while also representing the band as a whole, which is formed by Matevž Počič (guitar), Peter Smrdel (bass), Gaj Bostič (drums) and Aljaž Novak (backing vocal).
