On German producer and Aleph label founder Aera's latest release, the coalescing of influences from the past forty years of electronic music is audible. From the early electronic-style noises that warble over the bubbly acid pulse on the title track to the deeper than deep house of "Krystal Close" and the Mathew Jonson-sounding micro-trance melodies of "Keeping the Book", Running Hot is nothing if not adventurous and diverse. Innervisions also deserves praise for its choice of remixer; Steve Rachmad is not the most immediate name one would associate with the German label, but he does a fine job here, turning "Keeping the Book" into a deep, pulsing techno track, accentuating the original version's beautiful spacey-ness.
