“Introducing . . . Chris Cornell” might be a better title for this solo debut (due Tuesday), because the former Soundgarden singer and primary songwriter takes a couple of dramatic steps away from his grunge-rock past.

First, he trades in the old band’s sonic aggression for arrangements that lean on more traditional and accessible styles, ranging from strong, McCartney-ish melodic strains to searing R&B; seductiveness to exotic, Bowie-like moodscapes--all of which showcase better than ever one of the great voices in contemporary pop. Indeed, Cornell’s singing is so spectacular--both soaring and soulful--that it’s easy initially to focus on it rather than what he is telling us. But the message is Cornell’s second breakthrough.

With Soundgarden, Cornell chiefly expressed youthful anger and frustration, focusing on life’s obstacles and uncertainties. He hasn’t said goodbye to hard times, but the struggle is more internal.

While he certainly hasn’t found life’s silver lining, Cornell, 35, has learned that he is a survivor and that he can deal with the moments of depression and doubt. In the album’s loveliest tracks, including “Wave Goodbye” and “Sweet Euphoria,” he finds a way to reach for comfort rather than surrender to disillusionment.

Even when Cornell’s writing doesn’t match the heights of his vocals, he never settles for the safe or conventional. The result is a brave and impressive beginning of the second chapter in the Cornell expedition. The singer performs at the Henry Fonda Theatre on Tuesday and Wednesday.
