Supergroups seem back in vogue these days, from Tinted Windows to the Dead Weather to Them Crooked Vultures. Add fun. to that list. Despite the lower-case lettering, the trio of Nate Ruess (ex-The Format), Andrew Dost (ex-Anathallo), and Jack Antonoff (Steel Train) projects a huge sound on Aim And Ignite, its over-the-top debut. Produced by Red Krosss Steven McDonald, the album explodes with hooky, harmony-happy power-pop in the vein of the Raspberries, Big Star, and Badfinger. The robust tunes come front-loaded with piano, horn and string sections, gospel-style backup singers, and other gaudy adornments to match Ruesss theatrical singing, pitched between Broadway and Queen. There are highlights galore, from the Weezer-indebted midsection of opener Be Calm to the smoldering beauty of The Gambler. As power-pop goes, you cant get much more reverent than a song like All The Pretty Girls, and fun. reveal the true extent of their bombast on the nearly eight-minute finale, Take Your Time (Coming Home). Its a blast. With Hellogoodbye, Limbeck, My Favorite Highway. All ages.
