Even with the presence of special guest Timothy Leary, Seven Up sticks to its predecessor's penchant for bizarre, bluesy psychedelia on the first side while the second takes off into the deepest realms of space rock.
Fans of Leary may be a bit surprised, since he's but one of the five voices sprinkled throughout the album and sounds more like a poor man's Eric Burdon than an acid visionary might on tracks like "Right Hand Lover," "Downtown," and "Power Drive." Side two consists of three drawn-out space jams that conclude with a rushing of air quite close to a vacuum cleaner.
Except for the last bit, Seven Up is not quite the meeting of minds that acid and Kraut fans expected.
