Stephen Kellogg and the Sixers may not be the only band out there whose bread and butter is roots power-pop. And they may not even be the only band whos made a goofy music video featuring a marching band. (They enlisted UMass Marching Minutemen to dance in rows and spell out the band name with a marching formation in the video for the ultra-hooky Shady Esperanto and the Young Hearts.) But what they are is highly likable. Kellogg and the Sixers made up of Kit Karlson and Boots Factor, who switch between instruments, and the most recent addition, guitarist Sam Getz put no small amount of scrappy, amiable energy into doing what they do; See the Shady Esperanto video for instant proof. And theyre a hard-working band. Their self-released efforts led to a major label release, and when that didnt work out, they trucked on with indies, releasing The Bear on Vanguard last year. And, perhaps most importantly, theyre approaching the 1,000-show mark and still seem to be enjoying themselves.
