The Incomplete Triangle is the debut album by Lansing-Dreiden. It was released on April 6, 2004. It is a mix of various genres, divided into three parts of 4 songs each (hence the name of the LP). The first section of the album is the most rock-based, touching on garage rock and proto-punk among other styles. The middle section slows down the music a little with dream pop, ambient, post-punk and Britpop.
