This is one of his earlier efforts (1969) and it is one of the best records that focus on zappa's incredible composition and his revolutionary guitar playing (not to mention the Mothers, everyone plays really well, like all zappa albums)If you only know Zappa for his more popular songs, like "Don't Eat The Yellow Snow" This album is mostly instrumental, which is good for musicians, or classical and jazz fans. BEST SONGS: Theme From Burnt Weeny Sandwich, Holiday In Berlin, Full-Blown
