When it comes to Aerosmith, the vibe and communication within the band depends on who you talk to -- and on what day. Producer/songwriter Marti Frederiksen, a longtime collaborative associate of the band, told Billboard.com that Aerosmith have been "playing songs, putting together riffs, having fun, laughing and working from noon to 11."

However, MIA guitarist Joe Perry -- who has been critical about Steven Tyler taking the 'American Idol' gig and how it affected the band's future -- was not present at the sessions, due to a previous commitment. Frederiksen said the band is just digging in to the process, too.

Frederiksen revealed that the band crafted four songs in three days and will remain

working through Wednesday. Tyler has to report to his live 'American Idol' gig after that.

Last week, The New York Post published a story saying that the band couldn't work because of Tyler's 'Idol' gig. But his attorney, Dina LaPolt, responded with the following statement: "We are disappointed that The New York Post would print a Sunday story containing several false and misleading statements which was obviously not fact-checked, including comments made by someone who worked on the band's autobiography over 10 years ago."

LaPolt added, "These are the facts: Steven Tyler, Brad Whitford, Joey Kramer and Tom Hamilton are currently in the studio in Los Angeles writing new songs for the next Aerosmith album. The album is anticipated to be released later this year. Additionally, Dan Weiner, the band's agent at the Paradigm Agency, confirmed that the band will tour later in 2011 by saying, 'We are pleased to announce that Aerosmith has confirmed a tour of South America and Japan during 2011. Within the near future we will announce the cities and dates in each territory, and when tickets will be available for sale.'"
