Dem Hills is a studio based musical group created by Bruce Siekmann in 2000 to record songs written or co-written by him. The third and latest CD is called "The Rhumba Mystery" and features performances by 32 musicians playing on 12 songs. The styles of these pieces range from country, folk, rock, big band, classical, Spanish and eastern music. Lead vocals are handled by three female vocalists (Hannah Miller, Bev Conklin, and Kimberly Scheffey) and three male vocalists (Darren Schlappich, Bob Sica, and Bob Hogan) There are two instrumental pieces ("El Guirsta Reacio" and "Serenata a un Papagayo") This latest release features many repeat musicians as well as some new individuals. The themes cover a wide range of subject matter using current and past musical genres . Also, this CD includes sound bites between tracks as 'connecting devices. These sounds range from conversations to sound effects. The idea is to create a seamless audio visualization of a series of short stories or scenes . An "audio movie" . Because of the nature of this project, it's best listened to in it's entirety at one time.
