Aerosmith will release their new single in ''three or four weeks''.

The veteran 'Walk This Way' rockers are putting the finishing touches to the follow up to 2004's 'Honkin' On Bobo' and excited the record - which they say will sound ''modern and hi-fi'' - is almost complete.

Guitarist Joe Perry told Rolling Stone magazine: ''It's really close. We've started to mix. We've mixed a couple of the songs already, but I guess this week we're really kind of rolling into mix mode. We have a couple of tracks left to finish up, just to put some overdubs on, but we're kind of going from the final, final recording tracks to mixing this week.

''The record's gonna sound modern and hi-fi. We're not sitting around going, ''We're gonna do 'Night in the Ruts' again or 'Rocks' again. We want to make a modern sounding record, but the main thing is the energy that the early records had.''

New track 'Legendary Child', which is likely to feature on the record, will also appear on the soundtrack to new film 'G.I. Joe: Retaliation'.

Singer Steven Tyler said the recording of the song was great, especially Joe's contribution on guitar.

He said: ''It's gonna be slammin'. Joe was on fire. Wait, you'll see.''
