Wherever you mark their creative peak, Sunny Day Real Estate made one of the defining albums of mid-'90s emo with their debut, Diary, and its indelible opening combination of introvert anthems "Seven" and "In Circles." The press-shy band broke up amid frontman Jeremy Enigk's very public conversion to born-again Christianity, re-formed for two albums in the late '90s (minus bassist Nate Mendel, who was busy with Foo Fighters), and then went dark again. This tour marks the first reunion of the original lineup since 1995, and by all accounts the shows have been worth the wait. (Paramount, 911 Pine St, 467-5510. 8 pm, $25, all ages.)
