In addition, original members Al Burian and Dave Laney, along with Tim Remis, released an album under the side project Challenger in 2004.
The band became known for their eclectic stylings; their sound shifted from an experimental electronic format to heavier alternative rock in more recent years.
The album featured heavy drums following winding guitars and vocals alternating from contemplative and narrative to shrieking and visceral.
Milemarker also often employ a satirical or introspective slant toward social issues such as materialism ("Frigid Forms Sell You Warmth", "A Quick Trip to the Clinic", "Shrink To Fit"), technology ("Internet Relay Chat with the Central Intelligence Agency", "Server Error", "Ant Architect", "Virtual Sex"), and women's roles ("Food For Worms"), and have also referenced Orwellian ("New Lexicon") and apocalyptic ("Tundra", "Sun Out") themes.
Challenger, a more hard rock-oriented side project of Milemarker consisting of original members Al Burian and Dave Laney and newcomer Tim Remis, released their debut album Give People What They Want in Lethal Doses in 2004.
