Mat Brooke was the co-founder of softcore cult-favorites Carissa's Wierd, as well as a former member of Band of Horses. Mat left Band of Horses in 2006 to focus on the success of his current band, Grand Archives. Mat is likely noteworthy to the average reader for having contributed two songs and various guitar tracks to the Horses' acclaimed debut Everything All the Time, but his half of the Carissa's Wierd catalog is a more extensive document of his songwriting.
