Biography
The "Rivers Cuomo Band" (or RCB) is an informal name sometimes used by fans to refer to concerts featuring Rivers Cuomo, in Boston and Cambridge in late 1997 and early 1998, wherein Cuomo debuted new potential Weezer songs. The name exists mainly to differentiate from Homie shows from the same period. These shows were notable for being the first Weezer-adjacent shows to feature eventual Weezer bassist Mikey Welsh.
