As poetically spelled out by Ruben Blades in a salsa song, “There are eleven million histories in New York City.” There are many stories and storytellers in this mambo, and it won't be possible to mention all of them. However, a few individuals need to be acknowledged for their special contribution for this project to become a reality. First, the editors want to acknowledge all the contributors for their valuable work and dedication. We also want to give special recognition to John Michel, our editor at Columbia University Press, for his confidence in the significance of this collection since its early stages and for his strong support throughout the whole process. The analytical substance and writing quality of Mambo Montage significantly gained from the critical comments of our two main readers, Román de la Campa and Steven Gregory. Thanks to them for their invaluable work. Also thanks to Máximo Colón, Lisa Maya Knauer, and Amilcar Tirado-Avilés for providing their photos to be included in this volume. Last but not least, we also want to acknowledge the meticulously efficient labor of the team at Impressions Book and Journal Services, who coordinated the actual production of the book. Finally, Agustín wants to dedicate this book to the five women he loves most: Grandma Mami Angela González; his mother, Jenny Montes; Diana Coryat; and his daughters, Aiyana and Emma Lao, who represent the future hopes of this labor of love.
