Thanks for submitting, really like your designs! We like the use of the microphone. With #21 and #20 can you make the designs a little less neon - we like the designs, but the neon colouring makes it a little tacky.
Also, we don't want a heart in the designs so maybe remove the heart from #34 and #35.
I have included the B&W version for reference, since you don't know always know where you will put your logo, so it is a good idea for a band logo to work in single color. #44
