Alessandro Renato Rodolfo Lindblad (born 7 July 1991), better known by his stage name Alesso (Italian pronunciation: [aˈlɛsso]), is a Swedish DJ, songwriter, and record producer.

He has worked with numerous artists, including Tove Lo, Theo Hutchcraft, Ryan Tedder, Hailee Steinfeld, Calvin Harris, Katy Perry, Anitta, Usher, David Guetta, Sebastian Ingrosso, Liam Payne, TINI, and Stray Kids. He has performed at numerous music festivals, including Coachella, Electric Daisy Carnival, Creamfields, Tomorrowland, and Ultra Music Festival. In 2012, MTV named Alesso one of the "EDM Rookies to Watch" and Madonna, who invited him to open select dates on her MDNA Tour, called Alesso "the next big thing in dance music."

He was ranked 13th on DJ Magazine's 2015 list of the top 100 DJs and number 20th in year 2016 on DJ Magazine among the list of Top 100 DJs in the world. His debut full-length album Forever was released in 2015 by Def Jam Recordings.

Lindblad was born in Stockholm, and is of Swedish and Italian descent. He started playing piano at age 7, but became interested in electronic dance music when he was 16.

He first gained recognition with the release of his Alesso EP in 2010. In early 2011, Sebastian Ingrosso of Swedish House Mafia contacted Alesso and asked if he wanted to work together. Ingrosso introduced him to DJing and helped him with the production of tracks.

Since that time, Ingrosso has acted as a mentor for Alesso, who referred to the elder Swede as a "big brother."

Despite having learned to DJ in 2011, Alesso made his debut on DJ Magazine's list of the top 100 DJs at number 70 in that same year.

One of the first songs Alesso produced with Sebastian Ingrosso was a 2011 track named "Calling" that reached number 2 on the Beatport charts. The song would later be renamed "Calling (Lose My Mind)" with an additional feature from Ryan Tedder. Alesso's 2011 remix of "Pressure" by Nadia Ali premiered at the #1 spot on The Hype Machine and was one of the most played EDM songs of 2011.
