Themes of spiritual transcendence and mental dysfunction aren’t usual subjects for popular music, unless you are Boston’s Sam Welch and you put them into the kind of techno music he is known for, or the pop of his new album, The Republic.

The combination pop/alternative pop instrumentation and playful lyrics full of quirky rhymes makes even a song with a title like “My Darling Human Condition,” or “The Tenuous Affair,” a song about the philosophy of Thomas Hobbes, not only interesting but fun.

“I had a lot of fun creating it this year,” said Sam, who since 2017 has put out an album a year, mostly in a style he calls “transcendental techno vox.”
