The poster boys of big beat, that hip amalgam of electronica and rock that has dug its way into the national consciousness via "The Rockafeller Skank," have been busy since their 1997 breakthrough, Dig Your Own Hole. DJ mix album, the reasonably decent Brothers Gonna Work It Out, should have been the clue, but Tom Rowlands and Ed Simons have clearly been raiding a library- sized record collection since their last offering of "original" music.
"Music: Response," the album's leadoff, starts like a ride on the Autobahn with Kraftwerk circa the mid '70s, with its analog synth blips and monotone computerwelt voices, before tossing in some ferocious beats to bring Krautrock into the new millennium. The mood carries through on "Under the Influence" with more Kraftwerk- styled noodlings. Meanwhile, their best instrumental effort is "The Sunshine Underground," an eight- and- a- half minute ride through chiming tones, wafting flute- like sounds, and sputtering and gurgling synths that intertwine with the briefest of dreamy vocals. Actually, it wouldn't have been out of place on the last Orbital album.
Surrender will receive a ton of hype based on its superstar guest appearances, and none more historically relevant than "Out of Control" with New Order's Bernard Sumner on vocals. Being electronic dance music freaks from Manchester, New Order is like the holy grail to the Chemical Brothers and it's easy to see why. The Chemicals share with their Manchester predecessors an obsession with hypnotic, melodic, dance beats. "Out of Control" works so well it could be a lost track from Low Life. After his turn on "Setting Son" with the Chemicals in 1996, Oasis' terminally out- of- style Noel Gallagher returns for another psychedelic, Beatles-esque anthem on "Let Forever Be," again snagging the rhythm track from "Tomorrow Never Knows" off Revolver. Surrender is both the Chemical Brothers most immediately satisfying work and, perhaps not coincidentally, the most like a rock album of their career. Unlike a fair share of techno, these songs feel like "songs," not a collection of clever samples and a race to the fastest BPM on the planet. Yeah, you can go out and buy your jungle, your trance, your trip-hop and your ambient, but why would you when you'd be sacrificing the greatest gift of all: Surrender's love and understanding

Taking the swirling eclecticism of their post-techno debut, Exit Planet Dust, to the extreme, the Chemical Brothers blow all stylistic boundaries down with their second album, Dig Your Own Hole. Bigger, bolder, and more adventurous than Exit Planet Dust, Dig Your Own Hole opens with the slamming cacophony of "Block Rockin' Beats," where hip-hop meets hardcore techno, complete with a Schoolly D sample and an elastic bass riff. Everything is going on at once in "Block Rockin' Beats," and it sets the pace for the rest of the record, where songs and styles blur into a continuous kaleidoscope of sound. It rocks hard enough for the pop audience, but it doesn't compromise either the Chemicals' sound or the adventurous, futuristic spirit of electronica -- even "Setting Sun," with its sly homages to the Beatles' "Tomorrow Never Knows" and Noel Gallagher's twisting, catchy melody, doesn't sound like retro psychedelia; it sounds vibrant, unexpected, and utterly contemporary. There are no distinctions between different styles, and the Chemicals sound as if they're having fun, building Dig Your Own Hole from fragments of the past, distorting the rhythms and samples, and pushing it forward with an intoxicating rush of synthesizers, electronics, and layered drum machines. The Chemical Brothers might not push forward into self-consciously arty territories like some of their electronic peers, but they have more style and focus, constructing a blindingly innovative and relentlessly propulsive album that's an exhilarating listen -- one that sounds positively new but utterly inviting at the same time.

The Chemical Brothers' second career-spanning compilation is basically a substitute for the first, including nine of the same tracks first reissued on 2003's Singles 93-03 and then making room for a few of the touchstones released between 2003 and 2008 (two of which are new to this collection). The early classics Chemical Beats "" and "Leave Home" are still among the best of their career, while "Block Rockin' Beats" and "Setting Sun" (featuring Noel Gallagher) found the mature Chemical Brothers quickly growing comfortable with a stadium-sized sound and profile. From there, the duo appeared to merely refine their approach, gathering in further psychedelic and house influences while they scored gradually more popular guests over the subsequent ten years. Brotherhood's track listing could easily be quarreled with, but it includes most of the approved highlights from each album, early or old, innovative or orthodox. One of the new tracks features an intriguing matchup, with Spank Rock's Naeem Juwan joining the ChemBros for "Keep My Composure," a rather clever piece of acid hip-hop. [A deluxe version of Brotherhood included a special treat for fans, a bonus disc including all ten of the "Electronic Battle Weapon" tracks that found the Chemical Brothers working out tracks on white-label before they debuted as major-label work.]
