Aventura is an American bachata group formed in The Bronx, New York. With the lineup always consisting of the members Romeo Santos, Henry Santos, Lenny Santos, and Max Santos, they are regarded as one of the most influential Latin groups of all time. All of the members are of Dominican descent, although Romeo is also half Puerto Rican on his mother's side. They were the first major bachata act to have originated in the United States instead of the Dominican Republic. The group was integral to the evolution of bachata music and are the pioneers of the modern bachata sound.
