First time I saw Sleeper Agent, the big engine that could ("big engine" cuz there's 6 members in the band ya see), was in a small club in Omaha in 2011. I thought there were about 50 people there. Alex from the band corrected me last night, stating, "dude, there were like 5 people". Hahaha. 

To see this band go from that show to performing on David Letterman last night really made me proud. To watch them OWN it last night. Even better. This band is going to be around for awhile. Dive in now.
