I run a free music showcase website featuring up and coming guitar bands from the UK & the US. It's a labour of love borne out of a love of music and personal experiences. It also promotes associated businesses (studios, photographers, etc). Inclusion for bands is free but exclusive as the standard is very high. Businesses are guaranteed (free) inclusion.
It's only 4 months old but has already been endorsed by friends from the music industry: Anthrax's Joey Belladonna, Funeral for a Friend's Ryan Richards, producers Greg Haver & Romesh Dodangoda (FFAF, Manics, Bullet for my Valentine, etc), LA based concert promoter Gina Zamparelli and UK promoter/dj Emma Scott.
Please check out paradiddlesplectrumsandposers.com to enjoy some new bands.
If you would like to recommend a band then please do, or if you are (or know of) a business that would like a plug, there is a contact form on the site. Recommendations are very welcome
