The final collaboration between singer Julie Driscoll and Brian Auger's Trinity was Streetnoise in 1969. As a parting of the ways it was to be the Trinity's finest moment. A double album that featured 16 tracks, more than half of them with vocals by Driscoll, and the rest absolutely burning instrumentals by the Trinity. Streetnoise was a record that may have been informed by its era, but it certainly isn't stuck there. The music here sounds as fresh and exciting as the day it was recorded.

"Azteca was a Latin jazz-rock-fusion group formed in 1972, started by Coke Escovedo and his brother Pete Escovedo, who had just finished stints with Latin rock pioneering band Santana. Azteca was the first large-scale attempt to combine multiple musical elements in the context of a Latin orchestra setting, and featured horns, woodwinds, multiple keyboards, three vocalists, guitars, drums, and multiple Latin percussionists.
Onstage, the band consisted of between 15-25 members, and toured with acts including Stevie Wonder. Other notable Azteca alumni included drummer Lenny White, bassist Paul Jackson, vocalist Wendy Haas, trumpeter Tom Harrell, guitarist Neal Schon, vocalist Errol Knowles and percussionist Victor Pantoja. The group was also a musical starting point for Latin percussionist Sheila E. (the daughter of Pete Escovedo), who appeared with the band as a teenager. Two albums were released on Columbia Records, the self titled Azteca (1972) and Pyramid of the Moon (1973), before the band split up.
On September 15 2007, a number of the surviving members of Azteca performed together for the first time in more than 30 years in Hollywood, California. The concert was recorded for an eventual DVD release."

For this set, Ernestine Anderson (who is joined by pianist Monty Alexander, bassist Ray Brown and drummer Jeff Hamilton) mostly sings very familiar songs, doing her best to uplift such tunes as "Summertime," "God Bless the Child," "Satin Doll" and even "You Are My Sunshine" and "Sunny." Ernestine's voice sounds fine and her interpretations reasonably fresh…
