News about artists in the lineup for Jazz Fest this year:

The Decemberists (Sunday, May 1) have recorded a lovely pop song, “The Great Outdoors,” for the Nickelodeon kids show Yo Gabba Gabba:

Also, music industry critic/analyst Bob Lefsetz wrote today about Mumford and Sons (Friday, April 29). In his piece, he says:

We could debate all week long what’s fueling Mumford’s sales, but the fact is Mumford & Sons’ “Sigh No More” sold 31,000 copies this week to place number six on the SoundScan chart. They’re almost at 750,000 copies. And number 10 on the 2010 chart was Ke$ha, with 1,143,000 copies sold.

In other words, in the world of recorded music, Mumford & Sons are SUPERSTARS!

Also, Amos Lee’s (Saturday, April 30) new album Mission Bell debuted at number one according to SoundScan, but it’s a mixed honor because it set the record for the lowest-selling number one—43,000 copies in the first week.
