On the just-released Go, Anna Fermin' s Trigger Gospel try on any manner of influences over nine tracks. "Where My Heart Begins" is classic country in the style of Loretta Lynn, with modest flourishes from a barroom piano and Fermin's strong, sweet voice singing words of romantic perseverance. By the next track, "Further Along," classical piano arpeggios and a spoken-word intro turn into a four-on-the-floor rocker, complete with an Abbey Road-inspired background chorus. The rest of the disc dabbles in ballads, roadhouse twang and a little bit of Memphis soul. Think of it as a sampler of that amorphous musical landscape we call "Americana," with Fermin and company the ideal musical chameleons you want as tour guides.
