Anthrax singer Joey Belladonna is also using his vocal chords for different purposes, as he did voiceover work for the new iOS and Android app 'Letter Avalanche.' Described as a "new type of word game where gravity, physics, and nerve all come into play," the title enables gamers to strengthen their vocabulary and coordination in one fell swoop.

"I had a great time doing the voiceovers for it (and I am) glad they asked me," said Belladonna. "We're all proud to put a game together we think everyone will have fun playing. I hope to do more in the future."

The goal of the game is to spell as many words before they reach the top of your respective device. Various power ups enables players to increase their scores as well as lengthen their survival, and with every 15 words that are spelled, the difficulty levels are increased. Developed by Tweaking.com, 'Letter Avalanche' also boasts no advertisements during game play, which is a rare luxury in free-to-play apps.

As for Anthrax, the band will release a live DVD they shot in South America later this year. Although the group have discussed a follow up to their 2011 studio album 'Worship Music,' Belladonna hinted that they are just in the preliminary stages. Fans of the outfit were also treated in March to their EP 'Anthems,' which offered their renditions of such classic rockers as Thin Lizzy's 'Jailbreak,' Cheap Trick's 'Big Eyes,' and AC/DC's 'T.N.T.'
