The subtropics are the geographical and climatical zone of the Earth immediately north and south of the tropical zone, which is bounded by the Tropic of Cancer and the Tropic of Capricorn, at latitudes 23.5°N and 23.5°S. The term "subtropical" describes the climatic region found adjacent to the tropics, usually between 23.5 and 40 degrees of latitude in both hemispheres.

According to climatologist Glenn G. Trewartha, a subtropical region should have at least eight months with a mean temperature of 10 °C (50.0 °F) or above. His revision of the Köppen climate classification assigns to such areas the letter C, while others zones encompassed in the original Köppen group C class would be considered part of group.

American climatologist John F. Griffiths in his book Applied climatology described the subtropical zone as having a coldest month of between 6 °C (42.8 °F) and 18 °C (64.4 °F) and assigning to this group the letter B, while the original B group of Köppen taxonomy would be spread over the various temperature-based groups.

Kevin Johansen (born 1964 in Fairbanks, Alaska, USA) is an Argentine-American rock musician. Born to an Argentine mother, Marta Calvet, and an American father, he lived most of his childhood in the San Francisco Bay Area, but moved with his family to Buenos Aires at the age of 12. Later he moved to Montevideo, Uruguay, where he learned to play guitar.

Johansen made a brief appearance in the local rock scene with the band Instrucción Cívica with Julian Benjamin in the 80s who released two albums Obediencia Debida in 1985 and Instrucción Cívica in 1986, but went to New York in 1990. There he met and married his Argentine wife, with whom he has a daughter. He played in the CBGB's club for long years, until he created the group The Nada, and in 2000 recorded the album with the same name, a mix of different Latin sounds with modern pop, funk and rock.

During the same year, and with the new album in his hands, he returned to Argentina, where he currently lives. The album, released by Los Años Luz, was relatively successful and Johansen and the group went on tour as far as Spain (album edited there by K Industrias).
