On 13 July 1985 Machinations performed three tracks, "Pressure Sway", "My Heart's On Fire" and "No Say in It", for the Oz for Africa concert (part of the global Live Aid program). It was broadcast in Australia (on both Seven Network and Nine Network) and on MTV in the US. The group developed a cult following in dance clubs during the mid-1980s. "The Canberra Times" Andrew Ferrington felt they "have to be one of the best dance bands in the country at present. And "Big Music" is one of the best Australian dance albums about. It captures beat, depth and harmony that could well have eluded the Machis. The second side is by far the better. Led by 'No Say', the four other songs combine to give an exhausting record of the band at its best".
