You won’t see it on the band’s website, but Rev Theory, who has played Springfield a time or two, recently made a temporary change to its rhythm guitar player. The new guy: Jacob Showalter, best known in The Springfield Scene as guitarist for Playing With Matches. Showalter worked for a time as a bartender at downtown karaoke bar (and periodic live music spot) Bugsy Malone’s and still keeps in contact with the staff there, and the news was posted to the Bugsy’s events blog. It’s not a long-term move from the sound of it, but it opens up possibilities for the future. It has happened before, after all. We’ll let you know more as we find out.
