The Rapids Theatre (1711 Main St., Niagara Falls) is presenting a pair of hard-rock shows that belie the notion that “modern rock” is a format tied strictly to the past. The heavy, guitar-based arm of alternative music – favored locally by radio station FM 103.3 the Edge – might not be lighting up the sales charts like it did in its late ‘90s heyday, but in terms of concert appeal, we can be assured that the audience for this music is still out there and eager to rock. The success of package tours like the Mayhem Festival, the Uproar festival and the Jaegermeister Music jaunt bear this notion out.

Buckcherry, led by vocalist Josh Todd, married the sleazy grandeur of midperiod Aerosmith to the glammed-out gluttony of Guns ’n’ Roses when it emerged in the latter ‘90s, and has continued to mine similar terrain ever since, as exemplified by the band’s biggest hit, “Crazy Bitch” in 2006. The group is poised to release its sixth album, “Confessions,” this spring. Meanwhile, Buckcherry is doing what it was born to do – touring, touring and touring. Buckcherry performs at 7:30 p.m. Sunday with guests Heaven’s Basement. Tickets are $25 advance, $30 day of show.

Stone Sour, the edgy alt-metal band led by Slipknot vocalist and successful author Corey Taylor – whose “Seven Deadly Sins” portrays his struggles with substance abuse – brings high-drama to its grunge-inflected metal. Nominated for several Grammy Awards over the past decade, the band has also become a major metal festival draw. Joined by nu-metal/alt-rock outfit Papa Roach, Stone Sour will take over the Rapids at 7 p.m. Tuesday. Tickets for the all-ages show are $32.50 advance, $37.50 day of show.
