Circa 1925, Louis Armstrong recorded his first Hot Five records - the first time he recorded under his own name. The records made by Louis Armstrong's Hot Five and Hot Seven are considered to be absolute Jazz classics and speak of Armstrong's creative powers. The band never played live, but continued recording until 1928.
The music was characterized by collective improvised solos, around melodic structure, that ideally built up to an emotional and "hot" climax. The rhythm section, usually drums, bass, banjo or guitar supported this crescendo, many times in the style of march tempo. Soon, larger bands and orchestras began to emulate that energy, especially with the advance of record technology, that spread the "hot" new sound across the country.
