Architects are a British metalcore band from Brighton, East Sussex. The band currently consists of vocalist Sam Carter, drummer Dan Searle, bassist Alex Dean and guitarists Adam Christianson and Josh Middleton. The band's first name was Inharmonic, which was swiftly changed to Counting the Days, and finally to Architects after a couple of years. They have released seven studio albums and one split EP with Dead Swans to date.

Architects have been referred to as being "pumped with both controlled rage and unhindered heart, accessible and ambitious, aggressive and beautiful". Considered alongside Enter Shikari as offering metalcore style to more mainstream audiences they have been described as metalcore, technical metal and progressive metalcore. Their music is characterised by choppy, complex guitar riffs, the use of obscure time signatures and rhythmic breakdowns, and for their guitarists alternating between a "down-tuned rumble" and "melodic punk" during songs. However the band's music isn't solely based upon technical proficiency and does use catchy riffs and choruses.  Architects have made various stylistic transitions and evolutions throughout their career, with the band citing their belief that each album should be distinct. On their second album Ruin, the band's sound was heavier and darker sound than on Nightmares. Hollow Crown maintains the aggression and technical proficiency of Ruin while incorporating more melody, catchy riffs and use of singing. The band also used synthesised instruments such as keyboards and drum machines. The guitars were tuned to Drop B with the lowest string at Ab, giving the "ability to create a really heavy low end sound on the bottom but still give a comfortable degree of tension on the higher strings." A prime example of their signature style is the song 'We're All Alone', with its technical, progressive guitar riffs and heavy, hardcore punk-influenced rhythmic breakdowns.  Their fourth album 'The Here and Now' represented a stylistic shift from their previous work considered "ultimately subjective" and "their most diverse". Described as going in a "clean-cut post-hardcore" direction, The Here and Now favours singing over screaming, anthemic choruses and hooks. The album still retains elements of their previous albums, however, including "tortured howls, frenzied riffs, and earth-shattering rhythms, albeit with a slightly more mainstream edge." The album includes the melancholy, glitchy electronica-based 'An Open Letter To Myself' and the rock ballad 'Heartburn' both lead into "rousing, fist-pumping choruses".  The band's fifth album Daybreaker featured something of a return to the heavier, more aggressive style of their previous albums, balancing this with the melody and hooks of The Here and Now. Daybreaker also features even more melodic, atmospheric tracks than usual, such as 'Truth Be Told, 'Behind The Throne' and 'Unbeliever'.  After the release of Daybreaker the band grew confident in playing much heavier music again, and cited that the key influence on the heavier style of their sixth album was to create the best songs for live shows. The album also incorporates blastbeats, which have not been used in any of the band's recordings since Hollow Crown.
