At the meeting the following day, Grupo Guaguancó Matancero was formed. The men agreed that the group would perform rumba and each member would be responsible for bringing his own respective instrument. The original members of Guaguancó Matancero were Florencio Calle “Catalino” (director, guagua), Esteban Lantri “Saldiguera” (vocalist), Juan Bosco (vocalist, claves), Hortensio Alfonso “Virulilla” (vocalist, maraca), Gregorio Díaz “Goyo” (tumba or salidor), Pablo Mesa “Papi” (segundo or tres dos) and Angel Pellado “Pelladito” (quinto). Later that year the great batalero (‘batá drummer’) and "quintero" (‘quinto drummer’) Esteban Vega “Chachá” joined the group.
