Californian Hard Rock act GERONIMO was forged by guitarist David Michael Phillips following the disbanding of KING KOBRA. The new band unit featured vocalist Thomas Adam Kelly and recorded demos with W.A.S.P. bassist Johnny Rod and QUIET RIOT drummer Frankie Banali. Phillips (a.k.a. David Henzerling) cited an earlier history as an ex-member of THE SCHOOLBOYS and had also previously had short, non-recording spells with both ICON and KEEL. The guitarist would also contribute to LIZZY BORDEN's 1989 album 'Master Of Disguise'.

Subsequently Phillips forged TOMCATS with the erstwhile ICON pairing of guitarist Dan Wexler and drummer Pat Dixon, vocalist Tommy Dean plus bassist Tom Rucci. When this unit folded Dean jumped ship to ASPHALT BALLET.
