“McCrum’s painterly aesthetic is consciously trashy, crummy. Part of this may be his concern for representing issues related to the working class, especially its representation in contemporary culture and academic discourse, what he considers is perceived as “trash culture.” However, McCrum’s capricious painting involves seeping elements within his disjointed perversions and microcosmo-linkages.”
— Séamous Kealy
McCrum's works are exploratios of codified behaviour, especially as it relates to the gallery situation. They cannot mean anything unless you interact with them, allow yourself to get sucked in, and then examine your own response. McCrum incorporates the act of viewing as a participation which the work needs for completion.
