The 1930s belonged to Swing. During that classic era, most of the Jazz groups were Big Bands. Derived from New Orleans Jazz, Swing was robust and invigorating. Swing was also dance music, which served as it's immediate connection to the people.
Although it was a collective sound, Swing also offered individual musicians a chance to improvise melodic, thematic solos which could at times be very complex.
The mid 1990's saw a revival of Swing music fueled by the retro trends in dance. Once again young couples across America and Europe jitter-bugged to the swing'n sounds of Big Band music, often played by much smaller ensembles.
