Illuminate

Shawn Mendes leaned further into guitar-led pop on Illuminate, making the voice and rhythm parts feel more closely connected than on his debut. The arrangements range from acoustic space to larger choruses, with a blues influence most audible when the playing is allowed to loosen up.

“Ruin” foregrounds that side of the record, while “Treat You Better” and “Mercy” aim for a more immediate pop impact. Together they capture a singer developing a broader sound without abandoning the direct melodies that first brought him an audience.
