Very cool work from vibist Cal Tjader – sounds that are different than some of the larger arrangements and concepts of his Verve Records albums of the mid 60s, and material that appears here for the first time ever! The set features a range of appearances that Tjader made on radio in Seattle – really well-recorded dates, done at the city's famous Penthouse nightclub – and featuring Cal's vibes in a stripped-down setting that's almost more of a throwback to his pre-Verve material for Fantasy records. There's excellent players throughout, especially on piano – as the keys are handled by Clare Fischer, Al Zulaica, and Lonnie Hewitt – all of whom did great work with Cal – working here in combos that feature plenty of percussion from Armando Peraza, and drums and timbales from Johnny Rae and Carl Burnett. The tunes are a nice mix of modes – some Latin, some bossa, lots straighter jazz – and titles include "Insight", "Davito", "Pantano", "Leyte", "Half & Half", "Bag's Groove", "Mambo Inn", "Morning", "Soul Burst", "Cuban Fantasy", "Love For Sale", "Reza", "On Green Dolphin Street", "O Morro Nao Tem Vez", "Fuji", and "Along Comes Mary".
