a bell, a whistle, a spray can being hit against a plastic beer case

Congotronics 2: Buzz'N'Rumble From the Urban Jungle, the follow-up to Konono No. 1, is out now. The Crammed Records website declares:

Hot on the footsteps of Congotronics 1, here comes a fresh selection of even more amazing sounds, courtesy of no less than seven electro-traditional bands from Kinshasa, all especially recorded and produced by Crammed's Vincent Kenis...These bands all draw on traditional trance music, to which they’ve incorporated heavily-distorted sounds generated by DIY amplification of their instruments.

And the Crammed site says it all about this track, which clocks in at a meaty 6:47:

Sobanza Mimanisa ('orchestra of light') are the resident band in Nganda Boboto, in the Selembao district where we recorded this piece. There are only five instruments here: a bell, a whistle, a spray can being hit against a plastic beer case, a guitar - whose 'power chord' style is very unusual in Kinshasa - and a likembe which manages to play the bass and solo parts at the same time.

Spray can, check. Now where can I get my hands on a plastic beer case??
