Liam McGrath (LeeUm)

Expect anything from Liam McGrath, who DJs as LeeUm. That's his approach, and it keeps a party guessing. He started out in house, and these days he leans toward a heavier hard groove sound, a shift that tracked the Dublin collective SafeHaus, which he founded before moving from Ireland to Melbourne. He's a multi-genre DJ, so the set can bend to the room. But his real strength is energy, so he suits a late party that wants to keep going well past midnight.
