Modest Mouse frontman Isaac Brock is collaborating on new material with former Smiths guitarist Johnny Marr, a spokesperson for the revered indie rock act confirms. Marr has traveled from England to visit Brock in his Portland, Ore., home base in recent weeks to work on tracks earmarked for Modest Mouse's next album, tentatively due later this year via Epic.

The band has been off the road since last fall after completing extensive touring in support of its 2004 album "Good News for People Who Love Bad News," which peaked at No. 18 on The Billboard 200 and sold an eye-popping 1.4 million copies in the United States, according to Nielsen SoundScan.

It spawned the biggest hits of Modest Mouse's career in the form of "Float On" and "Ocean Breathes Salty," which peaked at No. 1 and No. 6 respectively on Billboard's Modern Rock chart.

As previously reported, Marr is finishing the second album with his band the Healers, which is due this spring. He will also be heard on five tracks on vocalist Jane Birkin's new album, as well as the next project from singer/songwriter Lisa Germano.
