LISTEN TO: Red Hot Chili Peppers - 'Strange Man' and 'Long Progression'

Red Hot Chili Peppers have unveiled two new tracks – scroll down to listen.

The two songs – 'Strange Man' and 'Long Progession' – are the first of 18 new singles the band are set to release over the next six months and will be released tomorrow (August 11).

All the tracks were recorded during the band's sessions for their 2011 studio album 'I'm With You', and will be released as nine double A-sided 7'' singles over the next six months.

The next release will feature 'Magpies' and 'Victorian Machinery' and is scheduled for release on September 11.

Drummer Chad Smith recently said the band had been working on new material while frontman Anthony Kiedis was recovering from foot surgery earlier this year.

"Those are just waiting," Smith says. "We'll go back to those when we start writing again, I'm sure - or not. We're just always trying to come up with new stuff; usually the latest and greatest is what we use, but you never know. If there's something that's really good or if Anthony's really connected to any of them, that sometimes has something to do with it, so we'll see."
