Ever since Jump Time started performing in  the NJ/NY area in1998, bandleader/arranger & harmonicist Dennis Gruenling has developed a fat, swinging, horn-like sound, and a reputation for pioneering a new role for the  harmonica that has been grabbing attention from critics all around the globe. Playing diatonic and chromatic harmonicas, you can hear his blues, swing and traditional  jazz  influences, which come together to form a sound that is leading a new direction for the instrument in all roots music.
Each member of Jump Time is respected in their own field, and Dennis is not afraid to let them all shine during the course of any Jump Time performance, incuding new guitarist Dave Gross, and talented vocalist Gina Fox.

Jump Time has played on stages from The Chicago Blues Festival to The Jazz Company in Disney World, to Six Flags Great Adventure, to BB Kings in NYC. Along the way they have shared the stage with such acts as B.B. King, Little Sammy Davis, Rod Piazza &  The Mighty Flyers, Little Charlie & The Nightcats, Kim Wilson and Steve Guyger.
