The label became quite successful in the 1990s, releasing music by Simon Wickham-Smith & Richard Youngs, KK Null, The Gerogerigegege, Circle, Splintered, Thurston Moore, Hijokaidan, and Merzbow, side projects by members of Amp and Skullflower and myriad 7" and 10" singles by experimental artists from the UK, US, New Zealand, the Netherlands and Japan.
Shortly before taking over the label, Johnson began editing a fanzine called Grim Humour, initially covering non-mainstream artists such as Big Black, Swans, Killing Joke, Lydia Lunch, Whitehouse and Sonic Youth.
The fanzine ceased in the mid-1990s but Johnson has since launched a new title, Adverse Effect, which has been praised by Record Collector and Ptolemaic Terrascope, lasted four editions and now can be found as a blogspot and via the Fourth Dimension website.
Although Fourth Dimension was dormant for a short while in the late 1990s, it has since relaunched with further releases from Merzbow and Circle, as well as albums by Johnson's own project Theme, The Fields of Hay and British sound artist Andrew Liles.
Besides the fact Fourth Dimension and Lumberton Trading Company continue to this day, Richard Johnson is still writing about music, is involved in the band Theme, plans to oversee a reissue campaign by his last group, Splintered and is working on a book devoted to his Grim Humour fanzine.
