The Summit format is used in jazz to bring together performers on a particular musical instrument. Though these recordings often feature other musicians (notably a rhythm section), the main instrument is focused upon in a celebratory way.
The saxophone quartet has since become a somewhat common format, and to a lesser extent the bass clarinet quartet. Additionally, all-percussion ensembles and a cappella groups are common and focus upon a single instrument in a similar way.
German MPS Records produced several albums of this type, including New Violin Summit, Alto Summit, Vibes Summit, The Gypsy Jazz Violin Summit, The String Summit, Trombone Summit and You Better Fly Away by Clarinet Summit.
