After the success of from UNDER THE CORK TREE, Fall Out Boy earned the right to indulge their whims. Fortunately, their instincts tend to serve them well. On their most adventurous album, Def Jam president Jay-Z introduces quot;Thriller,quot; while Kenneth quot;Babyfacequot; Edmonds produces groove-heavy hit quot;This Ain't a Scene, It's an Arms Racequot; and quot;Thnks fr th Mmrs.quot; with this album the band remains true to their punk-pop roots. Whether spicing up their recipe with R&B swagger or playing it straight, FOB are at their best when they crank up the volume.
