Most famous for his time with the Horace Silver Quintet in the late 50's and early 60's, and then with his own quintet through the late 60's, Blue Mitchell recorded 5 albums for Mainstream Records in the early 70's. These albums were not received as well by critics as his "traditional" hard bop albums (a common theme when jazz musicians "sold out" and played in a more funk-influenced style). This is perhaps the funkiest of the Mainstream albums, with killer groove following killer groove following killer groove, and almost 4 decades after it was recorded, the album still feels fresh and relevant.
