Maurice White's astrological sign, Sagittarius, has a primary elemental quality of fire and seasonal qualities of earth and air, according to classical triplicities. Sagittarius in the northern hemisphere occurs in the autumn, whose element is earth, and in the southern hemisphere, it is spring, whose element is air. Hence the omission of Water, the fourth classical element. Based on this, he changed the band's name, to "Earth, Wind & Fire". White held further auditions in L.A, adding Michael Beal on guitar, Chester Washington on reeds, and Leslie Drayton on trumpet. White was a percussionist and lead vocalist. Drayton served as the group's arranger. Trombonist Alex Thomas completed the then ten-man lineup. Warner Bros designated Joe Wissert to be the band's producer.[6][12][20]
