for band in musical_groups:
print(', '.join(band))

Don't forget the closing parentheses for your print statement. *
The "for" keyword can be thought of as "for each". You can think of the first line of a for loop as: for each x in thing:.... On each loop the x becomes the sub item of the main item that is being looped over. Example:
for x in "apple": print("x now equals: ", x)
Output: x now equals: a x now equals: p x now equals: p x now equals: l x now equals: e
Therefore you'll want to be working with the sub lists in the musical_groups list, which you have already called: band, in the first line of your for loop. Then you'll just need to: ", ".join(band)
