"SENNA by Mahogany Frog" is the group's sixth full-length release. Lush with soaring synth-scapes, waves of blistering guitar feedback and sound-art segments consisting of field recordings, tape collage and analogue electronically-generated sounds, it is easily their heaviest and most challenging record to date. Often the music is hot and gritty, capturing the power of the band's live performance: the rhythm section throttles forward fiercely, laying a foundation for rapidly shifting melodic themes and sounds. At times the material is exploratory and dramatic, displaying layers of MIDI-controlled sequencers, razor-crisp glitch-beats, moody tonal washes and infectious, hip-hop-esque grooves. The orchestration on "SENNA" is largely mysterious, with highly overdriven, reverb-drenched synths, guitars and electronics trading roles and smoothly and swiftly. Along with the enthusiasm and tonal proficiency of engineer Jean Paul Peters', Mahogany Frog have created a cinematic art-rock masterpiece that aims to re-evaluate the conventional roles of instruments and how they contribute to a broader composition.
