Query: Title says: - Nothing serious. I tell you it's a lie!

At last the great Roy Hargrove comes back to the way he must have never got away from. This is pure, golden Jazz and it is very serious.Roy Hargrove in the Jazz tradition from his early recordings with a new group and with Slide Hampton playing trombone in no more than three out of the eight tracks. Great!The same uptempo swinging tracks and slowdown ballads with a samba track (what a delight!)which have marked Hargrove's Jazz albums.A great 2006 surprise to celebrate Hargrove's return to his roots after a long time trying new ways, boring ways.By the way, this is the true 'new way' for Hargrove: brand-new and creative compositions by members of the group, one by Hargrove, an inspired 'Day in Vienna' by Slide Hampton plus one only standard, the great Bronislau Kaper's 'Invitation' from the self-titled movie picture. Well balanced!A delicious toast to Jazz! Cheers!
