The Mall plays post-hardcore with aspects of screamo and indie rock. But the most identifiable characteristic of their music is the use of keys. The have an 8-bit feel at times, and definitely dominate the musical landscape of the songs. Without the use of keys I would say that there is really nothing about these songs that stand out. I suppose you could liken The Mall to a more discordant and mathy version of Murder City Devils. A more current equivalent would be These Arms are Snakes.
