This is a real killer slab! I've been waiting for both since hearing them on the dubs section of this site (big up SDM for grabbing those). Echo chamber is a very tech track with crunchy bass and some cool bleepy sounds followed up with an awesome st of stabs from DJ Mayhem's classic track "fierce". As usual the vibe is very streamlined and futuristic and is bound to be a big hit. The B side is a total oldskool frenzy with some real good chord stabs and tweaky analog synths that are straight out of 1992 (a bit like hardcore heaven is a way I think) which is all backed up by a nice solid beat. Runnin!
