This was Shakira in her pure rock best long before she got commercial. This along with Donde Estan Las Ladrones were her best work. Listening to Estoy Aqui you can hear snippets from other rock classics as her later American hit Underneath Your Clothes seemed to take its beat from Aerosmith's Dream On. Shakira is Baranquillera, from the same city as my family. She studied guitar with the same woman who gave my son piano lessons (taping his fingers to keep them straight). Shakira rebelled against the bayanato classic sound of Colombia to mix Lebonese sound with classic American Rock and nowhere does she do it better than this disc. I hope one day she comes out with English Language version of these songs so American audiences can appreciate these brilliant songs!
