The year has only just begun, but 2018's concert calendar is already filling up with a healthy helping of package tours uniting some of classic rock's biggest acts.

Last month, Foreigner announced they'd be sharing a bill with Whitesnake and Jason Bonham later this year – and now comes word that Journey and Def Leppard can be expected to embark on their own co-headlining run, reportedly starting in May. 1/19 Update - the 58-city tour has been confirmed, full details can be found right here.

Details of the Journey/Def Leppard tour haven't been revealed yet, but confirmation seems to have been offered by guitarist Neal Schon, who tucked it away at the end of the caption on an Instagram post promoting his guest appearance at the G3 show in Oakland on Jan. 14. Noting that Def Leppard guitarist Phil Collen is part of the lineup for this edition of the Joe Satriani-led tour, Schon added, "Journey and Def Leppard comin' soon!"

The bands' plans were also mentioned in a recent profile piece on Journey drummer Steve Smith — and again, while specific details remain under wraps, the feature described Journey's next round of dates as "a six-month tour" alongside Def Leppard, adding that plans call for the shows to begin in May. This tour will serve as the latest in a series of co-headlining packages for Journey; in recent years, they've shared stages with a long list of fellow rock vets, including the Doobie Brothers, Santana, Asia, and the Steve Miller Band.
