A protégé of Swedish House Mafia’s Sebastian Ingrosso, Alesso (born Alessandro Lindblad) is the latest Swedish DJ-producer aiming for global club domination with his debut album. Aside from a couple of ponderous, buzz-killing instrumentals, Forever is one long rave: Skyscraping synths, jackhammer beats and crossover-ready guest vocalists like Tove Lo (joining her compatriot for an EDM tune that flips David Bowie’s "Heroes") keep fists and endorphins pumping. There’s the occasional dose of melancholy on tracks like the Ryan Tedder collaboration "Scars" — but the Kylie Minogue-sampling "Cool" is pure summer-jam bliss.
