 Early Junk Yard had none of these but instead developed a characteristic layered percussion sound based on improvised instruments.However, by 1986, the only contributing improvised instruments were plastIC buckets and other things in replication of the standard go-go three roto-tom/two timbales configuration.That year, the band scored their first major hit, and arguably their signature song, "Sardines," which earned them airplay outside of the D.C. market.
