"In five years, Helena Hauff has gone from a resident DJ at the sticky, sweaty Hamburg club Golden Pudel to one of the current techno club and festival circuit's most thunderous selectors - blending acid house, electro, and post-punk into industrial techno, EBM and wiggling downbeat house jams ... her second album, Qualm, is a victory lap. It is, on paper, an uncomplicated beast: a live hardware workout of claustrophobic, rhythmic acid techno. But her ability to draw out harmonic elements from the cacophony of it all is deft - that cassette tape feel is still evident".
