***MAHJONGG is basically a bar band who got lucky. With The Long Shadow of the Paper Tiger they will rule 2010. Their previous album Kontpab announced a big noise in the music scene of 2008. Since then, they’ve partied around the world and come back to invent a new style of music they call Chicagotronics: a wall of sound command center with drums and humans. They sing together and dance all crazy and there’s this laser going. It’s great. The Long Shadow of the Paper Tiger features their first protest song (“Grooverider Free”), which is actually an extended version of a previous single (Pun alert: “Free Grooverider”). Following a closing gurgle-sax on “Gooble,” comes “Miami Knights” where our dance detectives take that smooth boat through choppy waters. The album continues with layers of keyboards, guitars, and percussion parts that wind around each other almost like a fugue—an intrinsic groove that rarely fails to amaze and inspire. No one with ears will listen and be depressed.
