Indie rock quartet Horse Mode formed in Billerica, Massachusetts, in 2010. Playing a mix of rhythmic math rock with tinges of prog and some '90s alternative energy, the band was started by vocalist/guitarist Jay Powers and drummer Ryan Sunderland, eventually incorporating bassist/vocalist Joel Gray and guitarist Dave Boz in 2011 and 2013, respectively. Friends since high school, the Lowell-based four-piece played in different band incarnations in the years prior to Horse Mode. They released a six-song demo, Remember The Dinosaurs, in 2012. Packed with crunchy jams, their sound recalled the complexity of Battles and Minus the Bear and the jagged edges of Fugazi and Built to Spill. Their official debut LP, All You Ever Talk About Is Jazz, was released in 2015 on Ocelot Records. - Neil Z. Yeung, Rovi
