There was a lot of carping online about the price of tickets for the RAGE AGAINST THE MACHINE reunion tour and, to be fair, if your name is Rage Against the Machine and your prices are anywhere north of the FUGAZI line, you're kind of asking for it, and the prices were way way north of there. But the most expensive ones, the ones that cost several hundred bucks or more, were doing the double duty of trying to keep scalpers at bay while also raising money for charities along the tour route. And Rage's TOM MORELLO says the band raised more than $3 million for those charities in the first 48 hours. Touché... Longtime CHICAGO TRIBUNE music critic GREG KOT says farewell... CHAKA KHAN belongs in the ROCK AND ROLL HALL OF FAME and didn't deserve her early exit from THE MASKED SINGER last week, but the less said about her national anthem at Sunday's NBA all-star game, the better. (It kinda sorta rang a bell, though.) But JENNIFER HUDSON covering DONNY HATHAWAY in memory of KOBE BRYANT, wow. So many truths, so many tears... RIP JACOB THIELE, SCOTT SESSIONS and CHRIS HOPSON.
