It’s kind of funny to think about, but South Jersey four-piece Ages didn’t form to write regular old indie rock songs. It started as an excuse for four friends from the local punk scene to record original Christmas music every December. Having contributed to a baker’s dozen of the famed Arbor Christmas compilations, Ages have recently released their own anthology of all the holiday songs it has recorded over the years as a free download. It’s all here, from “Merried With Children (What to Expect When You’re Expecting Christmas)” to “Frankincense of Style” (featured on Helen Leight’s 12 Days of Christmas compilation in 2008) and the excellently-titled “Rolling Down The Ice Backwards.” Listen to it below, download it at Bandcamp and catch Ages this Saturday, December 22, as part of the 13th Annual Arbor Christmas Show.
