Alborán began his first world tour on 27 May 2011 in Madrid at the Palacio Vistalegre, and has since performed in many Latin American countries, among which are Argentina, Chile and Mexico. Following his success, he released his first live album, En Acústico, in November of the same year. It included acoustic versions of most of the tracks in his debut album, as well as two new songs and four bonus tracks. The song "Perdóname" (Forgive Me) was re-recorded featuring Portuguese singer Carminho, and was released as the first single of the album, peaking at number one on the Spanish singles chart on 13 November 2011, thus helping En Acústico to debut also at number one on the albums chart one week later, on 20 November 2011, and to top the Portuguese Albums Chart in January 2012.
On 19 December 2011, Alborán received the 2011 Best New Act award in Los Premios 40 Principales. Both his albums Pablo Alborán and En Acústico were featured in Spain's official list of top-selling albums of 2011, at number 1 and number 6, respectively, and singles "Solamente Tú" and "Perdóname" were the respective third and nineteenth best-selling songs in Spain in 2011.
