On stage Martin Dosh, who uses his last name as a stage moniker, is like a mad scientist. He runs around the stage playing one instrument and then quickly switching to the next. He loops each sound he makes, which creates stunning build-ups in each composition. Watching one man construct all this noise is captivating.

But sometimes watching Dosh can be distracting. His second release, “Pure Trash” is a nice reminder of how spectacular Dosh’s songs really are.

With a Rhodes piano, drums and programmed beats, a sampler and effects pedals, “Pure Trash” is dark and atmospheric at its core; yet music-box-like chimes result in charm and warmth.

What especially brings out the emotion in this instrumental album is the spliced samples Dosh adds of his family.

On the album’s single “Naoise,” named after his recently born son, a child asks softly and innocently “Is Naoise a word?” Underneath shuffling bass and fuzzy beats, Dosh crafts a beautiful soundtrack to fatherhood.

“Pure Trash” highlights Dosh’s growth (perhaps coming from playing drums in the local group Fog). His first album was impressive but compared to the new record, it sounds flat. “Pure Trash’s” layered textures are more radiant and obvious and it gives the album more diversity – from hip-hop to electronica to jazz.

With these layers along with the snippets of his family life, Dosh creates a very personal album – that’s hard to do on a mostly instrumental record.
