Modern rock outfit Filter is making headway on its fourth album, which it hopes to release next summer, according to posts by frontman Richard Patrick on the group's official Web site.

"This material is f***ing amazing, as I've said in the past," reads Patrick's latest missive, posted to the site on Christmas Eve. "I've got like 10 songs written. I'm really pleased with how it's all coming out."

Patrick has been writing songs with producer Rae Dileo and also notes that former Alice In Chains guitarist Jerry Cantrell stopped by the studio to contribute some riffs.

As previously reported, Patrick recorded earlier this year with the project Damning Well, featuring former Limp Bizkit guitarist Wes Borland, producer Danny Lohner and Josh Freese of A Perfect Circle. The "supergroup" contributed a song to the Lakeshore Records soundtrack to the vampire film "Underworld."

Filter's last album, "The Amalgamut" (Reprise/Warner Bros.), debuted at No. 32 on The Billboard 200 in August 2002.
