Boasting over three hours of music, Lo Esencial de los Mejores Duetos is a mammoth compilation of Latin pop duets, many of them very good albeit generally several years dated. With three CDs and a DVD, there's more than enough music here, and the affordable price point is certainly attractive. Moreover, the compilation has a lot of star power, with two artists teaming up on each of the 56 tracks. Some of the more notable male singers include Alejandro Fernandez ("Amor Gitano," "En el Jardin"), Aleks Syntek ("Duele el Amor"), Juan Gabriel ("No Me Vuelvo a Enamorar"), and Luis Miguel ("No Me Vuelvo a Enamorar"). Some of the more notable female singers include Camila ("Yo Soy Quien"), Julieta Venegas ("Sueños"), Gloria Estefan ("En el Jardin"), and Ana Gabriel ("Cosas del Amor"). Some of the more notable groups include Reik ("Que Lloro"), Ha-ash ("Ya No," "He Venido a Pedirte Perdon"), la Quinta Estación ("Algo Más"), and Sin Bandera ("Que Lloro," "Si la Ves"). Moreover, though most of the featured artists are Latin American, there are some Europeans, including Tizziano Ferro ("Mi Credo"), Joaquin Sabina ("Y Nos Dieron las Diez"), and Miguel Bosé ("Si Puedo Volverte a Ver"), and some Americans too, most notably Beyoncé ("Amor Gitano"). For sure, there's a lot to like about Lo Esencial de los Mejores Duetos, but it does have a few drawbacks. For one, all of these songs are dated by at least a couple years. Secondly, it's not put together with much care. The sequencing is somewhat random and the packaging is nothing special. Lastly, note that the DVD of videos replicates material found elsewhere on the compilation.
