Friday-Saturday: It’s the Basilica’s best lineup in years, partly because it doesn’t look like a rehash of other recent years. Friday night headliners Weezer played the Twin Cities’ biggest church party only once before and were a blast, wham-bamming the crowd with catchy rock radio hits such as “Island in the Sun” and even “Hash Pipe.” They will be joined by Nate Ruess, from the “We Are Young” hitmaking band fun.; Cities 97 brand soft rockers O.A.R. and Mat Kearney; local pop/punk mainstays Motion City Soundtrack, and ’90s alt-rocker Matthew Sweet. Saturday night’s top dogs, Wilco, are Basilica first-timers who’ve amassed critical praise and a devoted live following if not ample radio hits in 20 years. They top out an impressive Americana-flavored bill with ex-Rilo Kiley frontwoman Jenny Lewis and Alabama songwriting stalwart Jason Isbell, whose follow-up to his landmark 2013 album “Southeastern” comes out a week later. Saturday’s other acts include soul-pop party band Fitz & the Tantrums and poppy newcomers Fly Golden Eagle, Echosmith and Rachel Platten. (5-10:30 p.m. Fri.-Sat. $55/one-day, $100/two-day.
