“I wanted to dig under the darkest impulses of humanity for this album, and that is violence, selfishness, and destruction,” says Benjamin Tod, guitarist, vocalist, and primary songwriter of Americana trio Lost Dog Street Band. The Muhlenberg County, Kentucky-based group’s latest album, its fifth overall, Weight Of A Trigger, out March 29, is a potent distillation of its outlaw heartache soul. The dark impulses Tod sings about are simply the demons that have driven him since he was a teen.

At 16, Tod left home to play music on the streets. Since then, he’s lived under bridges, rotted in jails, sought shelter hopping freight trains, battled addiction, and seen friends turn blue in the face and die. Though Tod has been aimless, and destructive, he’s always been prolific through exorcising his demons in song. Even if that meant writing songs at 7 a.m. in dank and dark basements strung out on drugs and drunk.

His companion in life and music, Ashley Mae, is an accomplished fiddle player and harmony singer. The pair met in the Nashville punk scene when Tod was 15, and Mae was 17. They share in a tumultuous love affair that’s defied adventures, and misadventures. The couple formed Lost Dog Street Band in the winter of 2010. The duo’s vision was to carry on the tradition of the American troubadour with fine Americana songcraft and starkly real storytelling.

Today, Tod and Mae are joined by bassist Jeff Loops of the beloved roots band, Deep Chatham. The three-piece group’s latest, “Weight Of A Trigger,” is a portal into when Americana was peopled by sensitive outlaws who pleaded for salvation in song. The 10-song collection spans old-time music, Appalachian folk, redemptive country blues, and winsome balladry. Each song is elegantly essential, using teardrop pedal steel guitar, delicate fingerpicked passages, emotive harmony vocals, and stately violin touches as delicate dynamic touches.
