A shake-up to Paramore’s lineup hasn’t slowed the group down.

The poppy alt-rock act is touring now behind its first album recorded without two of the band’s founding members, lead guitarist Josh Farro and drummer Zach Farro. The band will headline KeyArena at 7:30 p.m. Tuesday.

The buzz around the group has focused on inner-band strife for nearly as long as they’ve been a success, with rumors of a break-up starting all the way back in 2008.

But the group, led by singer Hayley Williams, hasn’t slowed down. While backstage strife led to the Farro brothers’ exit, the band soldiered on — and ended up scoring its first No. 1 record this year with its new self-titled album.

Expect to hear the singles off that album, “Now” and “Still Into You,” along with past hits, including “Crushcrushcrush” and “The Only Exception.”

Tickets are $41 to $61.47 at ticketmaster.com or 800-745-3000.

Jack Johnson also is back on the road, and will hit the Paramount Theatre at 6:30 p.m. Tuesday.

The laid-back singer-songwriter is touring now behind his September album, “From Here to Now to You,” another strong effort.

Johnson began his professional life as a surfer, learning the sport in Hawaii as a toddler and competing as a star athlete throughout his teenage years.

In his mid-20s, though, he changed gears and started recording music. Since 2002, he has scored a stream of beach-ready hits, when his debut single, “Flake,” climbed the charts.

The singer’s laid-back delivery and acoustic balladry have made him the type of crossover success beloved by college students and their parents alike.

Tickets are $69.90 at stgpresents.org or 877-784-4849.

On a very different note, long-running metal act Gwar is headed to the Showbox SoDo for a show at 7:30 Friday night.

The group, known for its grotesque and theatrical live shows, is touring behind its latest album, “Battle Maximus.”

Gwar has long been a cult act, attracting a specific type of metal fan with albums like “This Toilet Earth” and “Bloody Pit of Horror.” The resilient group formed in the late 1980s and has made a name for itself with over-the-top concerts that reveal in scatological references and bloody spectacle.

Tickets are $20 at showboxonline.com or 888-929-7849.

Sleigh Bells will play the following night, at 9 p.m. Saturday, at the Showbox at the Market.

The indie rock duo is touring now behind its latest album, “Bitter Rivals,” which saw release on Tuesday.

The Brooklyn-based band has made a name for itself — and won heaps of critical accolades — with its fuzz-drenched take on pop.

Tickets are $24 at showboxonline.com or 888-929-7849.

And finally, KT Tunstall will headline the Neptune Theatre at 8 p.m. Wednesday.

The singer is touring now behind her new album, “Invisible Empire/Crescent Moon,” a collection of songs about divorce and death that are darker than the singers more recent forays into pop.

Tickets are $26.50 at stgpresents.org or 877-784-4849.
