There can be a fine line between sin and salvation. And we saw both sides of it during Monday’s full house of late-night musical performances. Jane’s Addiction frontman Perry Farrell kicked things off on an uplifting note with the help of his tellingly named Kind Heaven Orchestra, imploring Let’s All Pray For This World on The Late Show With Stephen Colbert. The aptly named Bishop Briggs enlisted a small choir to help her out on the inspiring Champion on The Late Late Show With James Corden. Standing on a cross-shaped stage, Ty Dolla $ign mixed his messages with his medley of Purple Emoji and the booty-shaker Hottest in the City on The Tonight Show Starring Jimmy Fallon. Meanwhile, indie-rock sideman supergroup Mini Mansions extolled the virtues of vice with Bad Things (That Make You Feel Good) on Late Night with Seth Meyers. And finally, slacker-pop goofball Mac DeMarco dished up his typical tomfoolerly on Jimmy Kimmel Live, playing Finally Alone and Nobody while a bathing-suited bodybuilder flexed behind him — and then stripping down himself during 20 minutes of unaired performances. That much Mac (and cheese) is either heaven or hell, depending on your view. Can I get an Amen?
