HIT THE ROAD 10 p.m. on Audience Network. Swallow claims to be “America’s finest family band,” yet one minute into this new raunchy comedy, it’s apparent that the group is anything but. Jason Alexander, a co-creator of the show, plays Ken, a drummer and enthusiastic father who desperately tries to keep his wife (Amy Pietz) and four children committed to their mediocre project. While on tour as an opening act, Ken surprises his family with a tour bus, ending any privacy and setting off a whirlwind of hiccups. Their search for fame goes downhill when the headlining band cancels its tour, stripping Swallow of a big name to latch onto. The series is followed by the premiere of LOUDERMILK, starring Ron Livingston as a recovering alcoholic who is a substance-abuse counselor, at 10:30.
