The tour started at Arena Monterrey in Monterry on March 7, 2014, and ended at Hard Rock Cafe & Casino in Punta Cana, Santo Domingo Dominican Republic at August 27, 2016. Critical reception Allmusic's reviewer Thom Jurek said that "Santos proved himself an up-and-comer on Vol. 1, but on Vol. 2 he not only delivers on the promise, but emerges as a fully formed innovator. His collaborations underscore his reputation as a pop star, but that's just a natural byproduct of his talent and artistry". Julianne Shepherd of Rolling Stone stated that the album proved that "The former ringleader of bachata stars Aventura isn't known as the king of the romantic Dominican ballad for nothing".
