JG Jazz Band performs a variety of traditional, dixieland and swing standards for either background or dance music, perfect for any event in Washington D.C., Maryland, or Virginia.. The band performs with from three to six musicians. In the core trio, one musician plays both keyboard and trumpet (sometimes playing both instruments at the same time!). He can also perform on guitar or banjo when needed. The other musician is a bassist and the third musician is either a trombonist or guitarist. Two of the musicians sing if desired. The band is also rehearsed to performs with drums, saxophone and a female vocalist for larger events.
