All will be merry as Hobo gets down with its Holiday Hootenanny on Friday at House of Rock. The masters of the trademark Honkadelic sound will spin their South Texas-flavored Americana tales of beer trucks, corn whiskey, hot dogs and huisache while displaying top-notch musicianship that turns out serious jams even when tackling sometimes not-so-serious song topics. They’ll be joined by singer-songwriter Ty Dietz. Dietz comes armed with a guitar and a string of honest, engaging songs that are simply a joy to listen to. And there’s a promise of some holiday treats, too. Doors are at 9:30 p.m.
