The track that became "Pump Up the Jam" began life as "Technotronic" (which later became the project's official name), an original instrumental that Bogaert released under the name The Pro 24s.
The song became a worldwide success, eventually reaching #2 in both the US Billboard Hot 100 and the UK Singles Chart in late 1989/early 1990, becoming the first song in the house music genre to achieve commercial status.
