Blending elements of acoustic folk-rock, punk and stand-up comedy, Bobby Joe Ebola and the Children MacNuggits has purveyed serious social commentary smothered in parody since ’95. The duo exposes Burque to tunes like “Time is Crawling,” “Life is Excellent” and “Lake of Flies” on Sunday, April 7, at Blackbird Brunch. At high noon, get your grub on at Blackbird Buvette (509 Central NW) for only four bucks. The free, all-ages concert starts at 1 p.m. and features Ebola and company, along with Jumpsuit, Joe Cardillo and Russell Pyle.
