Memphis-based alt-metal quintet Saliva continues to support its latest album, "Blood Stained Love Story," which surfaced a year ago and reached No. 19 on The Billboard 200. The set has spawned mainstream-rock hits "Ladies & Gentlemen," "King of the Stereo" and "Broken Sunday," all of which are streaming at Saliva's MySpace page.

Drowning Pool is backing its August release, "Full Circle," which has scored mainstream-rock hits "Soldiers" and "Enemy," the latter of which is currently holding steady on rock radio charts. Those tracks and several others from the album are streaming at Drowning Pool's MySpace page.

The Texas-based rockers are coming off a tough couple of months in which much of their equipment was stolen in two separate robberies and bassist Stevie Benton was diagnosed with a neurological disorder, Bell's Palsy, and ordered off the road by his doctor. The disease, which causes paralysis of the face and sometimes sensitivity to sound, is often times temporary and will resolve itself in most cases, according to a press release.

"The unpleasant symptoms have passed and I'm feeling great," Benton said in a statement earlier this month. "The break has done me well and we're really eager to get back out there and play these shows with Saliva. We can't wait to see the fans and thank them for sticking with us, and we feel the best way to do that is give them a great rock show."

Drowning Pool is no stranger to hardship. The band burst onto the music scene with its platinum-selling debut, "Sinner," and first hit single, "Bodies," the year before original frontman David Williams died from a heart defect while on the 2002 Ozzfest tour. The band regrouped with singer Jason "Gong" Jones and released "Desensitiized" in 2004 but parted ways with that frontman due to "creative differences."

"Full Circle" brings in new vocalist Ryan McCombs, who fronted the rock band SOiL for seven years. McCombs' tense departure from the latter group is the subject of the song "Enemy."
