You may recognize Luke Top’s earthy intonation from the worldly dance music-informed outfit he co-founded, Fool’s Gold. Now, he’s now taking his voice to new places with a solo folk effort, Suspect Highs — a sometimes jazzy (“Reunion Island”), other times rockabilly (“Chariot”), all the time arresting affair. The product of an isolated post-tour convalescence, his debut LP (out March 4 via Grand Gallop Music) is no vanity project, but a deeply earnest and deeply honest confessional.
