You may remember Skapa's song 'Ska Polka' from 'Skankin' Round the World vol.5'. They were a band fom New Zealand that formed in 1988. They have only one full length called Easy Street from 1992 that was only released on cassette (no I don't have it...I've been desperately looking for it for years) that features 8 studio and 7 live tracks.
This is their first recording. It's a 4 track EP from 1992 called 'Ska Party' that was only ever released on cassette.
