No, i do not view it as self indulgent. I can see why people would think this way, however, i in no way agree with them.
The whole album is a celebration of music, and it shows. The Roots like to experiment, shown through their albums, shown through ?uestloves drum offs, shown by all the time they have spent with other artists.
Have they made this to make a profit? Yes. However, all The Roots albums have been made for a profit, as have every artist you listen to, signed or unsigned.
This CD is great. It's not only a fitting tribute to great music in the past, it shows how the music from the 60's and 70's is still relevant today. The majority of the issues discussed in these songs are still alive today. I recommend this CD!
