Lawrence, Kan.-based post-rock foursome The Appleseed Cast is relentlessly touring in support of their latest full-length, Illumination Ritual. While the work produced by the group doesn't exactly break new ground, that's not necessarily a bad thing. Making music together since '97, the Appleseed boys have damn near perfected the experimental indie/post-rock formula. Judge for yourself on Tuesday, May 21, at Launchpad (618 Central SW). Fellow Kansas crew Hospital Ships (who are signed to Graveface Records), sci-fi riffin' foursome Ghost Circles and acoustic indie-rock outfit Bellemah open the 21-and-over gig starting at 9 p.m. Tickets are only $10.

We could all use a little joyous expression in our lives. Get yours on Tuesday when choral group Expressions of Joy opens for the Isotopes by singing the National Anthem. It’s the chorus’ second invitation to perform before an Isotopes game. Founded in 2011, the group’s purpose is “to bring the joy of singing to individuals with developmental disabilities and/or other special needs.” According to Expressions of Joy, Inc. President Jeannine Kammann-Cessac, “not everyone might be able to lift a bowling ball or run in the Special Olympics, but everyone can at least feel the music, sway, smile and sing to our tunes.” The choir welcomes new members 17 and older; no special skills are required. For more information, visit abqjoy.com. Hear Tuesday’s performance at about 6:30 p.m. at Isotopes Park. (Lisa Barrow)
