With the release of Three Thirteen's seventh CD, THE SIGNAL, creator Mark Harrell has expanded and enriched the project's musical territory with the addition of voice and lyrics. Inspired by progressive and alternative artists such as Peter Gabriel, Yes, and Marillion, Harrell has constructed a 65 minute introspective exploration of personal and political sources. Stylistically diverse musical arrangements move between the upbeat, rhythmic 'Between the Dream', and the moody, ethereal 'Life Expedite'. Harrell's voice is intriguing and expressive, ranging from the high-key lament of 'For Today', to the dark crooning found in 'My Escape'. Right in the middle of this musical voyage is the only instrumental track, 'Inner Mission' - a guitar, keyboard and drum driven piece truly reminiscent of 70's prog rock, but with a uniquely acoustic emphasis. THE SIGNAL is a worthy addition to the Three Thirteen catalog, exploring new realms while staying true to the well-established compositional and emotive tradition of previous releases.
