The musical moment when a band transcends each member's top individual ability and breaks into a new level of playing. This can only be achieved when all members are deep in the groove and pushing each other. The result is usually described as "crunchy" or "heady" jams. It can also be used as "mothership" to describe the place the music went to.
Mannn Rob was wailing on that slap bass and Al followed him right up to the "mothership" with that jam

Trey was totally "mothershipping" on that hood jam, with Gordon dropping bombs right below him!

Jerry was "mothershipping" all over the place on Egypt '78
