Carl,
You know how some bands just have 'IT', that 'cool factor' that you just can't put you're finger on? Well, Jellyfish just shit that factor. Full of personality, a blaze of colour and even though they were a long way away from 'metal' I would have recommended their gigs to ANYONE.
Most of the other projects the ex-members have gone on to have been worthy of a listen to, especially UMAJETS.
Ex mainman ( and standing drummer!) Andy Sturmer has just produced the second MERRYMAKERS album, but I think you may know that already.
