Journey is among the more interesting cases in the history of rock music. They’ve maintained a steady touring presence for the better part of their career, despite the fact that enigmatic frontman Steve Perry — one of the more, um, interesting figures you’ll find in the annals of pop music — left the band nearly 20 years ago. In his place, the band now employs Arnel Pineda. Pineda, who first found fame in his native Philippines, has fronted Journey for the past decade, touring and releasing a couple of albums during that time. Can he wail like Steve Perry? No, but then again, few can. That said, Pineda and Journey have been a band long enough now that those in attendance should be in for quite an experience. Plus, Smart Financial Centre is a welcome addition on the Houston-area concert scene.
