Although final details are still being worked out, oddball sibling-led outfit Sparks will perform each of its 20 albums at 20 different shows next May and June at London's Islington Academy.

The performances will be in chronological order and feature "Halfnelson," "Woofer in Tweeter's Clothing," "Kimono My House," "Proaganda," "Indiscreet," "Big Beat," "Introducing Sparks," "No. 1 In Heaven," "Terminal Jive," "Whomp That Sucker," "Angst in My Pants," "Outer Space," "Pulling Rabbits Out of a Hat," "Music That You Can Dance To," "Interior Design," "Gratuitous Sax & Senseless Violins," "Plagiarism," "Balls," "Lil Beethoven" and "Hello Young Lovers."

Sources tell Billboard.com the 21st and final night of the run will feature a performance of the group's next album, which is as-yet-untitled.

Sparks, anchored by brothers Ron and Russell Mael, is beloved for its unclassifiable body of work, which ranges from the borderline disco of albums like Giorgio Moroder-produced "No. 1 in Heaven" to the symphonic touches of 2002's "Lil Beethoven."

But the group has never reached higher than No. 63 on The Billboard 200 (with 1975's "Propaganda") and No. 49 on the Billboard Hot 100 (1983's "Cool Places," which featured the Go-Go's' Jane Wiedlin).
