If this album were only the first half, I'd love it. The combination of Carlos Santana's blistering guitar solos and his Latin-rock-based band with the heavy, HEAVY gut drumming of Buddy Miles (soon to be a member of Jimi Hendrix's second great group, A Band of Gypsies, made for great, continually exciting music. "Lava," "Them Changes" (much better than on Buddy Miles's own group recording of the same time). The first half of the album is as exciting music as you could find at the time. The second half is a long, wandering piece entitled "Freeform Funkathyde," and the piece is about as good, and as dated, as its title. It's boring, heavy, and it doesn't go anywhere. But that doesn't matter because the first half is so good. I wish this group had played together longer.
