On Friday at KeyArena, multiplatinum, velvet-voiced vocalist Josh Groban performs in the round, allowing him to interact more intimately with concertgoers on all sides of a 360-degree stage. So don’t be surprised if he strolls right up to you at the Key and serenades you with “You Raise Me Up.” The focus of the concert will be songs from his sixth studio album, “All That Echoes” (Reprise Records). But the Los Angeles native has a long list of hits to add to the set list.
8 p.m. Friday at KeyArena, Seattle Center. $45.50-$95.50 (800-745-3000 or www.ticketmaster.com.
