Imperial Wax Solvent is a studio album by The Fall – the band's 26th – released in the UK on April 28, 2008. The album featured a new British-based lineup after the departures of the American musicians involved in writing and performing 2007's Reformation Post TLC, with singer and frontman Mark E. Smith, keyboardist Elena Poulou and bassist Dave Spurr remaining from the previous incarnation. They were joined by guitarist Pete Greenway (a guest guitarist on the previous album) and drummer Keiron Melling.
