Rock ’n’ roll is best heard live, of course, but the coming week offers a couple of notable opportunities for those who would prefer to be couch potatoes:
— After rave reviews following its debut at the Toronto International Film Festival, “Pearl Jam Twenty” — Cameron Crowe’s documentary about the venerable Seattle rock group — makes its broadcast premiere at 9 p.m. Friday, Oct. 21, as part of PBS’ American Masters series, airing locally on WTVS-Channel 56 in Detroit. The two-hour film features exclusive, previously unseen footage and interviews culled from more than 1,200 hours of footage. The film will be released on DVD on Tuesday, Oct. 24, and on Blu-ray Dec. 27.
— Coldplay won’t be touring on these shores until 2012, but it will be webcasting its concert in Madrid at 4 p.m. Wednesday, Oct. 25, with Vevo and YouTube. The Anton Corbijn-directed show comes the day after the British group releases its fifth album, “Mylo Xyloto.”
