Modern blues albums can be a tricky sell, so musicians add to the traditional sound in order to broaden their appeal. Not only is this tricky, it often leads to a tangle of blues, boogie-woogie, jazz and reggae with no real center or substance. Such is the case with Chris Daniels’ latest. The Spark starts out with the pseudo-reggae, jam-band-esque “50/50” and quickly disintegrates into sappy ballads (“Way Out West” and “If I’d Only Taken You Dancing” being the two main offenders). Daniels’ brand of blues has more in common with the Bacon Brothers than T-Bone Walker. And with nine of the 12 tracks clocking in at over four minutes, you may want to have your finger squarely on the skip button. Spark? It’s barely a flicker.
