Putting together a movie soundtrack is a tricky business. Many times it is nothing more than collection of throwaway songs from the hit bands of the day. Too many times the soundtrack is just an afterthought. This isn’t the case for the soundtrack of latest movie release “Spawn.” Following in the footsteps of 1993’s “Judgment Night” soundtrack, which paired up rock acts with rap groups, the soundtrack for “Spawn” mixes hard rock bands with electronic artists. The debut single “(Can’t You) Trip Like I Do,” features Filter and The Crystal Method. It sounds like a standard Filter song until the halfway mark. Then the Crystal Method add a healthy dose of dance beats, which tones down Filter’s tendencies to sound like nine inch nails. The biggest shock is the pairing of Metallica with DJ Spooky. Spooky reworks the classic Metallica song “For Whom The Bell Tolls (The Irony Of It All).” The song is turned into jungle remix, but retains much of the original guitar work and vocals. This new version captures the original’s energy while turning it into an indestructible dance tune.Unfortunately, not all the pairings workout. Orbital and Kirk Hammett, Metallica’s guitarist, turn in a boring guitar saturated version of Orbital’s “Satan.” Prodigy and Tom Morello’s “One Man Army” has none of either band’s energy or innovation. Morello is Rage Against The Machine’s guitarist.The surprises come from three of the more obscure acts. Stabbing Westward and Wink mix a snare drum drenched dance track with Trent Reznor Jr. vocals. It will make even the most reluctant person step onto the dance floor. Silverchair and Vitro’s contribution, “Spawn,” is one of the most aggressive songs on the soundtrack. The drums explode out of the speakers while lead singer Daniel Johns channels vintage Johnny Rotten. Finally, Incubus and DJ Greyboy’s “Familiar” has a jazzy almost R&B vocal sound, a driving guitar, Dr. Dre style keyboards and a hip hop drum track. It’s one of the most striking songs on the disc.As a whole the soundtrack is a pretty evenly divided between good and not so good. Some of the collaborations just don’t catch fire.
